📋 Clinical Stem — Contraception Consultation
A patient presents to discuss contraception — new start, method change, or emergency situation.
"A 26-year-old woman attends her GP requesting contraception. She is currently using condoms with her long-term partner and is keen to explore a more reliable method. She has no significant past medical history documented. Her LMP was 3 weeks ago and she has regular cycles. She does not smoke and has a BMI of 24."
This stem can represent any contraception encounter. The presenting patient may want to start, switch, or stop contraception — or may attend for emergency contraception. Adapt the consultation to the specific scenario.
Scenario A — New start (no medical history) Young woman with no contraindications; explore LARC vs user-dependent methods and match to lifestyle.
Scenario B — Side effects on COC Patient experiencing mood change, weight gain or irregular bleeding on combined pill; UKMEC re-assessment and method switch.
Scenario C — Emergency contraception Unprotected sex or missed pill; determine most effective EC method based on timing; assess ongoing contraception need.
Scenario D — Post-partum or breastfeeding New mother; COC is contraindicated while breastfeeding under 6 weeks; POP, implant, IUS and Cu-IUD all appropriate choices.
Scenario E — Peri-menopausal or complex medical history Older woman with migraines, hypertension or thrombotic risk; navigate UKMEC categories carefully; consider non-hormonal options.
Key variables to adapt for Age and smoking status (COC risk threshold), migraine with/without aura, personal or family DVT/PE, breastfeeding status, enzyme-inducing medication, desire for amenorrhoea, future fertility plans, and STI risk.

collapse
Contraception history is both clinical and relational. The most effective method is the one the patient will actually use consistently. Your role is to identify medical contraindications via UKMEC, uncover hidden concerns (fear of hormones, reproductive coercion, fertility anxiety), and match method to lifestyle — not to prescribe your preferred option.
🎓 Consultation opener — use existing information first
"I can see from your notes you've come in today to talk about contraception — it would be really helpful if you could tell me a bit more about what's brought you in and what you're hoping for."
Asking for the LMP or current method before allowing the patient to explain their agenda costs Relating to Others marks — it signals data-gathering over patient-centredness and signals a tick-box consultation style.
1A — Start with an open question: let the patient lead, then move to targeted questions
Question to askWhy it matters clinicallyChanges what?
🟢 OPEN QUESTION — always start here"Tell me a bit more about what's on your mind about contraception today — what would you like from this appointment?" Allows patient to set agenda; reveals hidden concerns about side effects, fertility, relationships or STI risk before you impose a structured clerking. Scores Global Skills & Relating to Others.Prevents the trap of assuming the patient just wants to start the pill — she may be here about emergency contraception or wanting to stop. DDxPsychosocialRx plan
Current contraception"What are you using at the moment, if anything?" Identifies method failure (missed pill, late injection), establishes baseline, clarifies why they are attending now.A patient on DMPA requesting EC has missed her window; a patient on COC with breakthrough bleeding needs UKMEC reassessment. DDxRx
Last menstrual period"When was your last normal period, and are your cycles usually regular?" Excludes current pregnancy (essential before IUD/IUS insertion and before COC start). Irregular cycles raise PCOS or premature ovarian insufficiency.A period >5 weeks ago with unprotected sex = pregnancy test before any hormonal method or IUCD. DDxSafety
Smoking status and age"Do you smoke, and how many cigarettes a day?" COC is UKMEC 4 (absolute CI) in women ≥35 who smoke ≥15 cigarettes/day; UKMEC 3 at <15/day. Age 35+ + any smoking = switch to progestogen-only method.The single most commonly missed UKMEC contraindication in GP practice. RxReferral
Migraines"Do you ever get migraines? If so, do you get any visual disturbance or weakness before the headache?" Migraine with aura = COC UKMEC 4 (absolute CI) due to increased ischaemic stroke risk. Must distinguish from migraine without aura (UKMEC 2).Progestogen-only methods (POP, implant, IUS) are UKMEC 1 in migraine with aura. RxSafety
Personal / family DVT or PE"Have you ever had a blood clot, or has anyone in your close family?" Personal DVT/PE = COC UKMEC 4. First-degree relative with DVT/PE <45 years = UKMEC 3. Screen for Factor V Leiden or thrombophilia before starting COC if strong family history.Combined pill increases VTE risk approximately 3-fold in average population; far higher with thrombophilia. RxReferral
Blood pressure and cardiovascular history"Have you ever been told your blood pressure is high, or do you have any heart conditions?" Uncontrolled hypertension (≥160/100) = COC UKMEC 4. Hypertension adequately controlled = UKMEC 3 (use with caution). BP measurement mandatory before COC start.Women on antihypertensives with controlled BP may use COC under close monitoring with specialist input. RxReferral
Breast health and cancer history"Any personal or family history of breast cancer? Any breast lumps you've noticed?" Current or recent (<5 years) breast cancer = UKMEC 4 for ALL hormonal contraceptives. Undiagnosed breast mass = UKMEC 3. Past breast cancer >5 years ago = UKMEC 3.Cu-IUD is the only contraceptive that is UKMEC 1 regardless of breast cancer history. RxReferral
Current medications"Are you taking any other regular medicines, including anything herbal or bought over the counter?" Enzyme-inducing drugs (rifampicin, carbamazepine, phenytoin, topiramate >200mg, St John's Wort) reduce hormonal contraceptive efficacy — switch to Cu-IUD or use higher-dose COC with barrier.Rifampicin reduces efficacy even of injectable and implant — Cu-IUD preferred during TB treatment. RxDDx
Future fertility plans"Are you planning to have children at any point, and is timing important to you?" Guides method choice: LARC best for long-term contraception but patient who wants to conceive within 6 months may prefer POP or barrier to avoid insertion/removal delays.DMPA delays return of fertility by up to 12 months — important if patient has a timeline for pregnancy. RxPsychosocial
STI risk"Are you in a stable relationship? Do you use condoms at all?" No hormonal or intrauterine method protects against STIs. Dual protection (condom + LARC) recommended in new or non-exclusive relationships. Screens for GUM referral need.Routine STI screening before IUD insertion reduces PID risk; chlamydia/gonorrhoea NAAT should be offered. RxReferral
Previous contraception experience"Have you used contraception before? What worked well or caused problems?" Prior experience predicts adherence and acceptability. A patient who stopped the pill due to mood changes may benefit from a progestogen-only method or Cu-IUD.Always ask specifically about mood, libido, bleeding pattern and reason for stopping previous methods.

Safeguarding Considerations — Consider in Every Consultation

Contraception consultations are a key opportunity to identify harm. Reproductive coercion — where a partner controls, sabotages or pressures contraceptive decisions — affects up to 1 in 5 women in abusive relationships and may present as repeated requests for emergency contraception or unexplained contraceptive failures.
🏠 Reproductive Coercion & Domestic Abuse
  • Repeated EC requests without ongoing method despite previous discussion
  • Partner removes condom without consent ("stealthing")
  • Patient seeks contraception without partner's knowledge (fear of harm)
  • Patient unable to choose own method — partner controls decisions
  • Signs of physical abuse, FGM, or forced marriage
👴 Under-16s — Fraser Guidelines
  • Must assess Gillick/Fraser competence before prescribing
  • Patient must understand advice and its implications
  • Encourage parental involvement but cannot be mandated
  • Document Fraser assessment in full in clinical records
  • Consider safeguarding concern if sexual partner is significantly older
👤 Learning Disability & Capacity
  • Assess capacity using Mental Capacity Act 2005 framework
  • Contraception for someone lacking capacity requires best-interest meeting
  • Involve advocate or IMCA as appropriate
  • Consider if contraception is being requested by carer rather than patient
💊 Self-Harm & Mental Health
  • Depot-medroxyprogesterone (DMPA) associated with mood deterioration — ask about mental health before prescribing
  • Patient with severe depression requesting EC: explore context for self-care and support
  • Enquire about current mental health if requesting contraception following assault
  • Post-assault: direct to ISVA / rape crisis support
If a safeguarding concern is identified: Document clearly in clinical records. Do not confront alleged perpetrator in consultation. Follow local safeguarding pathways — for adults, use MARAC referral if DASH risk assessment indicates high risk. For under-18s, refer to children's social care if immediate risk of harm. All GP practices must have a named safeguarding lead.

1D — ICE: Ideas · Concerns · Expectations — in every consultation, not just SCA
💡 Why ICE matters in contraception — not a tick-box exercise

Contraception decisions are deeply personal and influenced by misinformation, cultural beliefs, prior negative experiences and partner dynamics. Without exploring ideas, you may prescribe a method the patient will quietly stop. Without exploring concerns, you miss the woman who is convinced the pill caused her weight gain or infertility. Without exploring expectations, you cannot meet them or constructively address unrealistic ones. ICE in contraception directly determines adherence, method satisfaction and patient safety.

💭 Ideas
"Before we go through the options, it would help me to know what you've already been thinking — is there a particular method you'd had in mind, or something you'd read about?"
Reveals preconceptions — patient who has already decided on the pill may resist LARC discussion unless her ideas are acknowledged first. A patient who wants the injection because her sister uses it may not know about the bone density concern.
😟 Concerns
"A lot of women have worries about contraception that don't always come up in consultations — things like weight, mood, cancer, or effects on fertility. Is there anything along those lines that's been worrying you?"
The #1 reason women stop hormonal contraception is perceived weight gain and mood change. Validating this concern and sharing evidence (COC increases weight by ~0.4kg on average in RCTs) enables an informed conversation rather than a dismissal.
🎯 Expectations
"What would make this appointment feel like it was really useful? Is there something specific you'd like to leave with today?"
Some patients want to leave with a prescription; others want information to think about; others need referral to a family planning clinic. Mismatched expectations lead to dissatisfaction and non-attendance at follow-up, even when the clinical content was appropriate.
1E — Psychosocial context: the person behind the contraception choice
🤝 How social context drives contraception decisions and adherence

A woman's ability to use contraception effectively is shaped not only by the pharmacology of the chosen method but by her relationship dynamics, economic circumstances, cultural background and mental health. A woman in a controlling relationship may not be able to use a visible or partner-dependent method safely. A woman with depression may discontinue DMPA, worsening both her mental health and her contraceptive protection. Addressing psychosocial context is not optional — it is the difference between a prescription and a plan that works.

👫 Relationship dynamics & partner attitudes

Partner resistance to female-controlled methods, cultural preference for male involvement in family planning, or coercive control all affect method choice. Some women cannot negotiate condom use without risk of violence.

"How does your partner feel about contraception? Is this something you feel able to discuss with them?"

If partner is resistant, consider "hidden" LARC (IUS, implant, DMPA) — not visible and partner-independent.

🌞 Cultural, religious & personal beliefs

Some faiths oppose artificial contraception (certain Catholic teachings, some Islamic interpretations). Others restrict specific methods (e.g., those perceived as abortifacient, such as Cu-IUD). Imposing a preferred method without exploring beliefs damages trust.

"Are there any beliefs — religious or personal — that might influence the type of contraception you'd feel comfortable with?"

Barrier methods or natural family planning may be the only acceptable option for some patients; respect this choice and provide evidence about relative efficacy.

🧠 Mental health & mood

Progestogen-containing methods (particularly DMPA) are associated with mood deterioration in women with pre-existing depression. DMPA may worsen depression significantly. POP less clear evidence. COC has mixed evidence.

"How has your mood been generally? Have you noticed any connection between your contraception and how you feel emotionally?"

For women with active depression, Cu-IUD or barrier methods avoid hormonal mood effects entirely.

🍼 Body image & weight concerns

Fear of weight gain is the leading reason women stop the pill despite limited evidence. DMPA is genuinely associated with weight gain (∼2-3kg over 2 years in some studies). Implant and IUS have less effect. Addressing this proactively prevents silent discontinuation.

"Weight and body image can be really important when choosing contraception — is this something that matters to you?"

Share evidence: COC & POP data shows minimal weight gain in RCTs; DMPA has genuine but modest effect.

📚 Adherence & lifestyle

Shift work, irregular sleep, frequent travel, or cognitive difficulties reduce pill-taking adherence significantly. A woman who works night shifts will often forget a pill taken at "the same time every day." Poor adherence is the leading cause of pill failure.

"How do you find it with remembering to take things at the same time each day? Does your day-to-day routine make that straightforward?"

Poor adherence predictors = strong indication for LARC (no user-dependence once inserted).

💌 Future fertility timeline

A woman who wants to conceive within 12 months should not receive DMPA (fertility delay up to 1 year after last injection) and may prefer a method with immediate return of fertility (POP, implant, COC, IUS).

"Thinking ahead, are you planning to have children at any point, and is the timing of that important to you?"

Fertility returns immediately on stopping POP, COC, and on removal of implant or IUS. Cu-IUD: immediate. DMPA: up to 12 months delay — counsel explicitly.

Step 3
Do I Need This Examination?
collapse
Examination in contraception consultations must be purposeful, not reflexive. Most routine contraception can be prescribed without a pelvic examination. The key mandatory examination is BP measurement before COC. Pelvic examination is required only for IUCD/IUS insertion. Each examination must change a clinical decision or it wastes time and may deter patients from accessing contraception.
ExaminationWhy it mattersWhat finding changes managementChanges management?
Blood pressure (mandatory)COC requires baseline BP — UKMEC 4 if ≥160/100 (uncontrolled); UKMEC 3 if 140-159/90-99 (monitor closely)BP must be <160/100 before COC start; recheck at 3 monthsBP ≥160/100 = COC contraindicated; switch to POP or Cu-IUDYES — mandatory
BMI / weightBMI >35 = COC UKMEC 3-4 (increased VTE risk). Weight >70kg reduces LNG-EC efficacy significantly.Desogestrel POP is weight-independent; Cu-IUD is weight-independentBMI >35 = advise Cu-IUD for EC; consider LARC over pillYES — EC & COC
Speculum + bimanual examinationRequired for IUCD/IUS insertion to assess uterine size, position, and detect concurrent cervicitis or pelvic tendernessMust be performed immediately before insertion — active cervicitis or large fibroids may prevent safe insertionFixed retroverted uterus / active cervicitis / uterine anomaly = defer insertion or referYES — IUCD/IUS
Abdominal examinationAssess for pelvic tenderness, guarding (PID), or palpable mass suggesting ovarian pathology in women with IUD and painNot required for pill prescribingPeritonism / guarding with IUD in situ = refer same-dayContext: IUD + pain
Breast examinationIndicated if new breast lump reported in history; undiagnosed breast mass = UKMEC 3 for hormonal methodsNot a routine requirement before every contraception prescriptionUndiagnosed lump = urgent 2-week wait referral; defer hormonal contraceptionContext: breast symptoms
Skin / implant site examinationCheck implant palpability at review (should be palpable under skin); non-palpable implant may have migratedOnly relevant at existing implant review, not at first presentationNon-palpable implant = arrange X-ray / specialist review; cannot rely on contraceptive effectContext: implant review
Cervical inspection (speculum)Visually check IUS/IUD threads are visible; overly short threads may indicate expulsion or displacementOnly at IUCD/IUS routine check or if patient reports symptomsMissing threads = arrange USS; if threads seen = device in situ, reassureContext: LARC review

Step 4
Do I Need This Investigation?
collapse
Investigations in contraception must answer a specific clinical question. The most important is a pregnancy test before any IUCD/IUS insertion or before starting combined hormonal methods when the LMP is uncertain. Routine blood tests are not required before prescribing the pill — but thrombophilia screening, LFTs, and STI screening have clear contextual indications.
InvestigationClinical question it answersWhat result changes management?
Urinary or serum pregnancy testIs this patient pregnant? Essential before IUCD/IUS insertion and before starting COC when LMP uncertain or >5 weeks agoPositive = cannot start COC / insert IUCD; refer to EPU urgently; check for ectopic features
Blood pressure measurementIs BP within safe range for oestrogen-containing methods? COC UKMEC 4 if uncontrolled (≥160/100)≥160/100 = absolute contraindication to COC; 140-159/90-99 = caution (UKMEC 3), use POP or Cu-IUD
Chlamydia / gonorrhoea NAAT (STI screen)Is there active STI that requires treatment before or alongside IUD insertion? (Reduces PID risk post-insertion)Positive chlamydia = treat before or at time of IUD insertion with doxycycline 100mg BD 7 days; positive gonorrhoea = defer insertion, refer GUM
HIV test (point-of-care or serology)Is patient HIV-positive? HIV-positive patients can use all methods but may require dose adjustment with certain ARVs that are enzyme inducersHIV + on enzyme-inducing ARVs (efavirenz) = Cu-IUD preferred; adjust hormonal method dose
Cervical smear (if overdue)Not part of contraception per se — but a contraception consultation is an opportunity to check smear status (NHSCSP: 25-64 yrs in England)Overdue smear = refer for cervical screening; does not delay contraception prescription
Liver function tests (LFTs)Is there active or significant liver disease? COC oestrogen is hepatically metabolised; COC UKMEC 4 in active hepatitis, cirrhosis, liver tumourRaised ALT/ALP + symptoms = investigate hepatic cause; defer COC; use Cu-IUD
Thrombophilia screen (Factor V Leiden, protein C/S, antithrombin)Does strong personal/family VTE history indicate inherited thrombophilia? UKMEC 4 for COC if thrombophilia confirmedPositive thrombophilia = all combined methods UKMEC 4 — Cu-IUD or progestogen-only only
Pelvic ultrasound (if IUCD concern)Is the IUCD correctly sited? Required if threads not visible on speculum examination or patient reports pain/expulsion symptomsIUCD outside uterine cavity = refer for removal under imaging guidance; use alternative contraception immediately
FSH / LH / oestradiol (peri-menopausal)Is this peri-menopausal woman still at risk of pregnancy? FSH >30 IU/L on two occasions 6 weeks apart suggests ovarian insufficiency but does not confirm infertilityFSH >30 = advise contraception for 1 year (if >50) or 2 years (if <50) after last period — cannot guarantee infertility

Reaching a Decision & DDx — Explained in Plain Language
collapse
Contraception "diagnosis" means matching the right method to the right patient. The lay explanation task is about helping patients understand why some methods suit them better than others, using analogies and plain language rather than medical nomenclature.
🗣️ Explaining the Options in Plain Language — say something like this

"There are a few different ways of preventing pregnancy and they work in different ways. Some, like the pill, you take every day — they're very effective when used perfectly but the effectiveness can drop if you forget to take one. Others, like the coil or the implant, once they're in place they work without you needing to do anything — they're the most effective options available. The right one really depends on your health, your lifestyle, and what matters most to you in terms of things like periods and side effects."

💬 Addressing the patient's own explanation — why it may not be the full picture

"The pill is the best option — it's what everyone uses."
"The pill is a great option for many women, but it depends very much on your health. For some women there are medical reasons to avoid it — like migraines with visual changes — and for others, something that requires no daily effort like an implant or coil might actually work better long-term. Can I run through what's best for your situation specifically?"

"I've heard the coil can make you infertile."
"That's a really understandable worry, and I'm glad you mentioned it. The evidence actually shows that fertility returns straight away when the coil is removed — there's no lasting effect on your ability to get pregnant. The coil only works while it's in place."

A — GP-managed contraception
GP can prescribe / fit

Combined oral contraceptive (COC)

Oestrogen + progestogen; UKMEC 1 if no CI; 99.7% perfect use; offers non-contraceptive benefits (period regulation, acne, dysmenorrhoea)

Non-hormonal; most effective EC within 5 days; 10-year device; heavier periods a common side effect; suitable for women wanting hormone-free contraception

DMPA (Depo-Provera)

3-monthly IM/SC injection; no daily effort; fertility delay up to 12 months on stopping; bone density reduction with prolonged use; caution in depression

C — Requires immediate management
Emergency / same day

Emergency contraception (EC) required

LNG-EC: within 72h (best <24h); UPA: within 120h; Cu-IUD: within 5 days (most effective). Time-critical — assess and prescribe immediately.

Unintended pregnancy on contraception

If Referral Is Needed — What the GP Does Before & During
collapse
Many contraception referrals can be avoided with GP-level skills. The key role of the GP before referral is to use a bridging contraceptive, exclude pregnancy, and address immediate safety concerns. IUCD/IUS fitting should be managed in primary care where possible — LARC uptake improves dramatically when insertion is offered at the same appointment as counselling.
ConditionUrgencyWhat GP does before referralWhat GP must NOT do
Positive pregnancy test — unintended Same day Exclude ectopic (pain? IUD in situ? prior PID?); refer to early pregnancy unit (EPU); provide non-directive information on options; document discussion; ensure follow-up plan Direct patient towards or away from termination without their lead; delay EPU referral if ectopic features present; fail to document options discussion
IUCD/IUS fitting (no GP trained) Routine Start bridging contraception (POP / barrier) immediately; prescribe bridging method at consultation; refer to family planning clinic or trained GP colleague; give written information on IUCD/IUS Leave patient without any contraception while waiting for appointment; fail to offer EC if recent unprotected sex
Suspected STI with IUD in situ Same day to 2 days Take NAAT swabs; start empirical antibiotic treatment per BASHH/NICE PID guideline (ceftriaxone + doxycycline + metronidazole); retain IUD unless no improvement at 72h; refer GUM if gonorrhoea suspected Remove IUCD before antibiotic trial; fail to treat empirically while awaiting swab results
Complex medical history (multiple UKMEC 3–4) Routine to 4 weeks Document all UKMEC categories; prescribe safest bridging method (Cu-IUD or POP if no CI); refer to specialist family planning (Margaret Pyke, community gynaecology) Leave patient without contraception; prescribe UKMEC 4 method; fail to document UKMEC risk assessment
Suspected non-accidental injury / reproductive coercion Same day DASH risk assessment; document safeguarding concerns; discuss safety planning with patient; refer to MARAC if high risk; inform safeguarding lead; offer ISVA contact Breach confidentiality without patient consent unless immediate risk of serious harm; confront alleged perpetrator; fail to document
Under 16 — Fraser assessment needed Routine Complete Fraser competency assessment; document in full; explore relationship and any age-related concerns; offer STI screening; provide contraception if competent — do not withhold to punish sexual activity Prescribe without Fraser assessment; breach confidentiality to parents against patient's wishes unless immediate harm; refuse contraception on moral grounds

Management — Expectation · Goals · Lifestyle · Drug Selector · Drug Cards · Psychosocial · Follow-Up · Safety-Netting
collapse
7A — Address the patient's expectation first: validate → explain → negotiate
🤝
Never dismiss the expectation — acknowledge it, share your reasoning, then agree a shared plan
1
Validate — name their expectation

A patient who arrives expecting the combined pill has often done research, spoken to friends, or had it before. Acknowledge that before redirecting.

"It sounds like you've been thinking about the pill, and that makes complete sense — it's one of the most commonly used methods."
2
Explain — share your clinical reasoning

If a medical contraindication exists, or if a more effective method is clinically preferable, explain why — using plain language and without dismissing their preference.

"Because of the migraines with visual changes that you mentioned, the combined pill isn't actually safe for you — it can slightly increase the risk of a stroke. But there are really good alternatives that would work just as well."
3
Negotiate — offer something today

Always leave with an agreed plan. If the patient declines LARC for now, give a user-dependent method with a clear invitation to revisit LARC when ready.

"Let's start with the mini-pill today — and I'll give you some information about the implant so you can have a think about it. There's no rush, and you can always come back when you're ready."
Key principle: Reproductive autonomy means the patient chooses their method — your role is to ensure that choice is informed and safe. A patient who insists on a method that is UKMEC 4 cannot be prescribed it regardless of autonomy; but your job is to explain why clearly and to offer alternatives, not to leave them without contraception.
7B — Why contraception matters: goals tailored to this patient
Treatment goals
✓ Prevent unintended pregnancy ✓ Menstrual cycle management ● Minimise hormonal side effects ● Period reduction / amenorrhoea (if desired) ● Preserve fertility for future plans ● Protect against endometriosis / HMB Annual STI screening discussion Patient-led method review whenever needed
Motivational language — tailored to the patient
"With the implant or coil, once it's fitted your risk of an unintended pregnancy drops below 1 in 1000 per year — far lower than with the pill, even when taken perfectly."
"You mentioned you're keen to get back to playing sport — the implant means you won't need to think about contraception at all for 3 years, which might suit you perfectly."
7C — Non-medication management: lifestyle advice tailored to contraception
Lifestyle advice in contraception must be specific and actionable. Vague "use condoms" advice is inadequate. Each recommendation should address a specific risk, name a concrete behaviour, and explain why it matters.
🌀
Dual Protection
Condom + effective contraception
Why it matters

No hormonal method or IUCD protects against sexually transmitted infections. Chlamydia is often asymptomatic and can cause tubal damage and infertility if untreated.

Practical advice

Use condoms consistently with any new or non-exclusive partner alongside your chosen contraceptive method. Free condoms are available through NHS community pharmacy and sexual health clinics.

Prevents chlamydia, gonorrhoea, HIV and other STIs
🚭
Smoking Cessation
Stop smoking before age 35
Why it matters

Smoking 15+/day at age 35+ makes the combined pill absolutely contraindicated (UKMEC 4). Smoking multiplies the arterial and VTE risk from oestrogen dramatically.

Practical advice

Refer to NHS Stop Smoking Services; offer varenicline or NRT. If stopping COC, switch to POP or LARC. Use contraception consultation as a teachable moment for smoking cessation.

Preserves access to combined pill options; reduces stroke risk
⚖️
Pill Adherence Strategies
Take same time daily (±12h POP, ±24h COC)
Why it matters

Typical-use failure rates are 7-9% per year for user-dependent methods vs <0.1% for LARC. The gap is entirely due to missed pills and inconsistent use.

Practical advice

Set a daily phone alarm; link pill-taking to a fixed daily routine (morning brush teeth, bedtime). Use the NHS 28-day pill checker if pills are missed. Consider LARC if adherence is repeatedly poor.

Reduces typical-use failure rate from 7-9% to 0.3%
⚔️
STI Screening
Annual screen if <25 or new partner
Why it matters

Asymptomatic chlamydia is present in up to 10% of sexually active under-25s and can cause PID, ectopic pregnancy and tubal factor infertility. Annual testing is recommended by BASHH.

Practical advice

Self-sampling kits available by post via SH:24 or sexual health clinic. Urine or vulvovaginal swab. Ensure testing is completed before IUD insertion to reduce PID risk.

Prevents PID, tubal infertility, ectopic pregnancy
⚖️
Weight & BMI
BMI <35 for safe COC use; EC efficacy at >70kg
Why it matters

BMI >35 increases VTE risk with oestrogen-containing methods (UKMEC 3-4). LNG-EC is significantly less effective at weight >70kg (BMI >26) — Cu-IUD or UPA preferred for EC.

Practical advice

If BMI >26 and requires EC, prescribe UPA or arrange Cu-IUD. For COC users with increasing BMI, recheck at annual review. Offer weight management referral if appropriate.

Reduces EC failure; reduces VTE risk from oestrogen methods
💉
Drug Interactions
Review medications before prescribing
Why it matters

Enzyme-inducing drugs (rifampicin, carbamazepine, phenytoin, St John's Wort) reduce hormonal contraceptive levels. Even the implant may be affected by rifampicin.

Practical advice

Always check for St John's Wort specifically (often not volunteered). If on enzyme inducer, switch to Cu-IUD or add barrier method. Stop St John's Wort if possible.

Prevents contraceptive failure due to drug interaction
7D — Prescribing guide: UKMEC-based decision algorithm
The FSRH UK Medical Eligibility Criteria (UKMEC) governs all prescribing decisions. UKMEC 1 = no restriction; UKMEC 2 = advantages outweigh risks (use with care); UKMEC 3 = risks generally outweigh advantages (avoid unless no alternative); UKMEC 4 = absolute contraindication (do not use). Always apply UKMEC before prescribing any hormonal method.
First choice — LARC (Long-Acting Reversible Contraception)

NICE recommends LARC as first-line for most women (NICE CG30 2019).

  • Implant (Nexplanon) — UKMEC 1 for most conditions; suitable post-partum, breastfeeding, migraine with aura
  • IUS (Mirena) — UKMEC 1; added benefit for HMB; 5–8 years; consider for women approaching menopause
  • Cu-IUD — UKMEC 1; only hormone-free LARC; most effective EC; 10 years; ideal if breast cancer history
LARC uptake at same appointment as counselling increases uptake 3-fold (NICE evidence)
Second choice — user-dependent hormonal methods

Appropriate when patient declines LARC or LARC is not yet accessible.

  • COC — check UKMEC 4 CIs first (migraines with aura, smoker ≥35, DVT/PE, BP ≥160/100); 21-day active + 7-day break or PH regime
  • POP (desogestrel) — ±12h window; suitable when COC contraindicated; no oestrogen; category 1 for most conditions
  • DMPA — 12-weekly IM or 13-weekly SC; caution depression, BMD concerns in under 18s & >2yr use
Always provide written information on missed pill instructions and when to seek additional contraception
Third — barrier and natural methods

Less effective but appropriate when hormonal methods are all contraindicated or declined on personal/religious grounds.

  • Male/female condom — only STI-protective method; always recommend alongside LARC in new relationships
  • Diaphragm + spermicide — hormone-free; requires fitting and instruction
  • Fertility awareness methods — effective with training (Sensiplan, Billings); not suitable for irregular cycles
Emergency contraception plan must be discussed for all barrier method users
Emergency contraception — timing algorithm

Method choice depends on time elapsed since unprotected sex, BMI, and drug interactions.

  • Cu-IUD: most effective (>99%) within 5 days; suitable regardless of BMI or drug interactions
  • Ulipristal acetate (UPA) 30mg — brand ellaOne: within 120 hours; UKMEC 2 if breastfeeding (withhold milk 1 week); not with enzyme inducers
  • Levonorgestrel (LNG) 1.5mg — brand Levonelle 1.5mg / Levonelle One Step (OTC as Emerres): within 72h (best <24h); reduced efficacy >70kg / BMI >26; use double dose (3mg) if BMI >26 + UPA unavailable
Do NOT prescribe both UPA and LNG together — antagonistic effect. Choose one.
Special populations — key UKMEC considerations
  • Post-partum breastfeeding <6 weeks: Implant, Cu-IUD, DMPA safe; POP safe from day 21; COC contraindicated
  • Peri-menopausal (>45 yrs): COC can be used to menopause if no CI; switch to HRT at 50 for menopausal symptoms; IUS provides endometrial protection for HRT
  • Enzyme-inducing medication: Cu-IUD only reliable method; if COC unavoidable use EE ≥50mcg + 7-day barrier after stopping inducer
  • SLE / antiphospholipid antibodies: UKMEC 4 for combined methods; POP UKMEC 2; Cu-IUD UKMEC 2

Combined Oral Contraceptive (COC)
Microgynon 30, Rigevidon, Ovranette, Levest (2nd-gen, lowest VTE); Gedarel, Marvelon (desogestrel); Yasmin, Lucette (drospirenone)
✓ Recommended
UKMEC 1 EE 20–35mcg + progestogen
✓ Prefer when
No UKMEC 3/4 contraindications; wants cycle regularity and predictable withdrawal bleeds
Endometriosis, dysmenorrhoea, acne, PCOS — non-contraceptive benefits
Perimenopausal woman wanting cycle control (continue to age 50 if no CI)
✗ Avoid if
Migraine with aura — absolute CI (UKMEC 4): ischaemic stroke risk
Age ≥35 + smoking ≥15/day — absolute CI (UKMEC 4)
DVT/PE history, thrombophilia, BP ≥160/100, breast cancer, liver disease
Obesity BMI >35, enzyme-inducing medication, breastfeeding <6 weeks
⚠ Side effects
Nausea (take with food); breast tenderness (often resolves 3 months)
Mood change — if significant, switch progestogen type or to Cu-IUD
Breakthrough bleeding — check adherence; if persistent consider switching preparation
🔬 Monitor
BP at 3 months, then annually; BMI annually
Review at any change in migraine, new VTE symptoms, or new liver disease
💬 Counselling

"Take one pill every day at roughly the same time. The pill is very effective when taken correctly, but it doesn't protect against infections — you'd still need condoms for that."

SCA pearl: Ask about migraine aura BEFORE prescribing COC. Missing this is a patient safety failure. "Do you ever get visual disturbance or weakness before a headache?" scores a Tasks mark.

Progestogen-only Pill (POP)
Cerelle, Cerazette, Feanolla, Zelleta (desogestrel 75mcg); Slynd (drospirenone 4mg); Noriday (norethisterone)
✓ Recommended
UKMEC 1 Desogestrel 75mcg daily
✓ Prefer when
COC contraindicated: migraine with aura, smoker ≥35, DVT/PE history — all UKMEC 1 with POP
Breastfeeding from day 21 post-partum; post-partum women not breastfeeding from day 21
Women wanting a pill without oestrogen-related side effects (mood, VTE, headache)
✗ Avoid if
Current breast cancer (UKMEC 4) — use Cu-IUD
Enzyme-inducing medication — reduces desogestrel levels; use Cu-IUD instead
Functional ovarian cysts possible — advise on incidental finding on USS
⚠ Side effects
Irregular bleeding (most common) — especially first 3 months; amenorrhoea common with desogestrel
Functional ovarian cysts — usually resolve spontaneously; reassure if found on USS
Mood change — weaker evidence than DMPA but counsel appropriately
🔬 Monitor
Annual review: side effects, adherence, STI risk, cervical smear status
No specific blood test monitoring required
💬 Counselling

"Take this at the same time every day — desogestrel gives you a 12-hour window if you forget. Your periods may change — they might become irregular or stop altogether, which is safe and normal."

SCA pearl: POP is the progestogen-only pill patients mean when they say "the mini-pill." Clarify — desogestrel (12h window) vs norethisterone (3h window). Desogestrel is preferred.

Subdermal Implant
Nexplanon (etonogestrel 68mg); fitted in upper inner arm
✓ Recommended
LARC 68mg etonogestrel / 3 years
✓ Prefer when
Poor adherence to daily pill; shift work, irregular routine; cognitive difficulties
Breastfeeding from day 21; same indications as POP but no daily action required
Wants highly effective reversible contraception with immediate return of fertility on removal
✗ Avoid if
Current breast cancer (UKMEC 4)
Enzyme-inducing drugs (rifampicin) — even implant levels may be reduced; Cu-IUD preferred
Patient cannot tolerate unpredictable bleeding pattern — warn thoroughly before fitting
⚠ Side effects
Irregular bleeding — most common; affects 20% significantly; improved with mefenamic acid or combined pill "bleed buster"
Bruising, localised pain at insertion site (resolves within days)
Rare migration of device — always palpate at review; non-palpable = specialist imaging
🔬 Monitor
Check palpability at 3-month review and annually; if non-palpable refer for imaging
Fertility returns immediately on removal — discuss at annual review if plans change
💬 Counselling

"Once it's fitted you don't need to do anything for 3 years. The most common issue is irregular bleeding — your periods may become unpredictable, lighter, or stop altogether. This is safe but I want you to know in advance."

SCA pearl: Counsel explicitly on irregular bleeding BEFORE fitting. Women who weren't warned are far more likely to request early removal. This counselling is a scored Tasks item.

Intrauterine System (IUS)
Mirena (52mg LNG, 8 yrs); Kyleena (19.5mg, 5 yrs); Jaydess (13.5mg, 3 yrs)
✓ Recommended
LARC LNG 52mg / 5–8 yrs
✓ Prefer when
Heavy menstrual bleeding (HMB) — Mirena licensed; reduces blood loss by >90%
Endometriosis, dysmenorrhoea — progestogenic suppression of ectopic lesions
Perimenopausal — provides endometrial protection for HRT oestrogen (Mirena licensed for this at any age ≥45)
✗ Avoid if
Current breast cancer (UKMEC 4); unexplained uterine bleeding (UKMEC 4)
Active PID or sexually transmitted infection — treat before insertion
Distorted uterine cavity (fibroids, bicornuate uterus) — may prevent correct placement
⚠ Side effects
Irregular bleeding / spotting for first 3–6 months — then amenorrhoea in 50%
Cramping pain at insertion — offer NSAID (ibuprofen 400mg) 1 hour before insertion
Expulsion risk 1 in 20 (higher in women who have not had a vaginal delivery)
🔬 Monitor
Thread check at 6-week post-insertion review; annual thereafter
Note expiry: Mirena 8 years for contraception (5 years for HMB/HRT use)
💬 Counselling

"Your periods are likely to become much lighter and may stop altogether — this is actually a benefit for most women. There will be some irregular spotting at first, usually for around 3–6 months."

SCA pearl: Distinguish IUS (hormonal, period-lightening) from Cu-IUD (non-hormonal, period-heavying). Candidates frequently confuse them. Period benefit = IUS; hormone-free = Cu-IUD.

Copper Intrauterine Device (Cu-IUD)
TT 380 Slimline, Flexi-T 380+, UT 380 Short
✓ Recommended
LARC / EC Copper device / 10 yrs
✓ Prefer when
Hormone-free contraception desired; all hormonal methods contraindicated or declined
Emergency contraception within 5 days — most effective EC available (>99.9%)
Breast cancer history (any stage) — only LARC with UKMEC 1 in breast cancer
✗ Avoid if
Wilson's disease (copper metabolism disorder) — absolute CI
Unexplained uterine bleeding; acute PID; known distorted uterine cavity
Heavy painful periods — Cu-IUD worsens menstrual blood loss; advise carefully
⚠ Side effects
Heavier, more painful periods — most significant side effect; may improve after 3–6 months
Cramping at insertion; perforation risk 1–2 per 1000 insertions
If pregnancy occurs with IUD in situ — likely ectopic; urgent EPU referral
🔬 Monitor
Thread check at 6 weeks; if threads not visible — pelvic USS
If fitted age ≥40 — can remain until 1 year after last menstrual period (post-menopause)
💬 Counselling

"The copper coil has no hormones at all — it works by affecting how sperm move. Your periods may become heavier initially. If you ever get pregnancy symptoms or abdominal pain, contact us urgently."

SCA pearl: Cu-IUD is the most effective emergency contraception available and works regardless of weight or enzyme-inducing medication. Mention this proactively — many patients don't know it can be used as EC.

Depot Medroxyprogesterone Acetate (DMPA)
Depo-Provera 150mg IM; Sayana Press 104mg SC
✓ Recommended
Step 2 150mg IM / 12 weeks
✓ Prefer when
Adherence to daily pill is difficult; no injection phobia; infrequent GP contact acceptable
Sickle cell disease — may reduce sickle crises; well-evidenced benefit
Endometriosis — amenorrhoea-inducing effect suppresses lesions
✗ Avoid if
Plans to conceive within 12–18 months — fertility delayed up to 1 year after last injection
Significant depression, anxiety or history of DMPA-related mood deterioration
Under 18 or >2 years use — bone mineral density reduction (usually reversible); review BMD if prolonged
⚠ Side effects
Irregular bleeding especially first 3 months, then amenorrhoea in up to 70% by 1 year
Weight gain — evidence of 2–3kg average over 2 years in some cohorts; counsel proactively
Delayed return of fertility — mean 7–9 months from last injection; up to 18 months possible
🔬 Monitor
BMI and weight at each injection appointment; bone density review if >2 years continuous use
Mood review at each appointment; stop DMPA if significant mood deterioration
💬 Counselling

"The injection lasts 12 weeks — you don't need to think about contraception in that time. Your periods will likely change and may stop, which many women find convenient. It can take up to a year for your normal cycle to return after stopping."

SCA pearl: Always counsel on fertility delay before starting DMPA. A woman who wants to conceive within 12 months should not receive DMPA. This is a scored Tasks item under safety-netting.

7G — Psychosocial impact of contraception: periods, mood, relationships & daily life
🤝
Living with contraception — what to tell every patient before they leave
The decision to start or change contraception affects far more than pregnancy prevention. Period pattern, mood, libido, body image and relationship dynamics are all directly shaped by method choice. Proactively addressing these impacts builds trust, improves adherence and prevents silent discontinuation — the most common cause of contraceptive failure in practice.
🧠
Mood & mental health

DMPA has the strongest evidence for mood deterioration in women with pre-existing depression. COC and POP have weaker, mixed evidence. Some women notice significant improvement in PMS with COC.

Ask at every review: "How has your mood been since starting this method?" If DMPA-related mood change is confirmed, switch to Cu-IUD.

Document any mood change attributed to contraception in clinical records with patient's own words.

"Some women find their mood is affected by hormonal methods — if you notice any change, please don't stop taking it suddenly, come and talk to me first."
💓
Libido & sexual function

COC reduces sex hormone binding globulin (SHBG), which can lower free testosterone and reduce libido. This may persist even after stopping COC in some women.

POP and implant have less clear evidence on libido. Cu-IUD has no hormonal effect on libido.

Ask about sexual wellbeing at annual review — it is not often volunteered but is a significant quality-of-life factor.

"A small number of women notice a change in their sex drive on hormonal contraception — if this happens to you, please bring it up and we can look at alternatives."
🙄
Menstrual pattern changes

All methods alter bleeding pattern. COC typically gives regular, lighter, predictable withdrawal bleeds. Implant/POP cause irregular unpredictable spotting. IUS causes amenorrhoea in 50%. DMPA amenorrhoea in 70% by year 1.

Warn of amenorrhoea explicitly before fitting IUS, implant or starting DMPA — unexpected amenorrhoea causes significant anxiety about pregnancy.

Reassure: amenorrhoea on these methods is safe — no blood is "backed up."

"It's quite common for your periods to become very light or stop on this method — that's a normal effect, not a sign of pregnancy."
👫
Relationships & partner dynamics

Some methods are not visible to partners (implant, IUS) — important for women in unsafe relationships who cannot disclose contraception use.

Male partner attitudes to contraception influence adherence significantly — address this without judgment.

Reproductive coercion (forced removal of IUD, pressure to stop pill) is a safeguarding concern — document and act on it.

"This method is completely private and your partner wouldn't know it's there — if that's something that matters for your situation, it's worth knowing."
🛠️
Work, study & daily life

Irregular bleeding from implant or POP can be disruptive to work and social activities. Amenorrhoea from IUS or DMPA may be advantageous for athletes and women with demanding schedules.

Pill-taking adherence is lowest in women with highly variable routines — LARC is a practical solution for these patients.

Post-insertion recovery from IUS (cramping for 1–2 days) may require brief time off work — plan the appointment accordingly.

"For the coil fitting, there might be some cramping for a day or two afterwards — it's worth planning it for when you don't have a heavy workload."
💌
Future fertility & long-term plans

Fertility returns immediately on stopping POP, COC, implant, IUS and Cu-IUD — no lasting fertility reduction from any of these methods.

DMPA is the exception: fertility delay of up to 12–18 months after last injection. This must be discussed before prescribing.

Offering LARC as a long-term option does not "lock in" a woman — all LARC methods are immediately reversible on removal.

"As soon as the implant is out, your fertility is back to what it was before — there's no need to wait before trying to conceive."
7H — Follow-up schedule

4
LARC expiry review (implant 3 yrs; IUS 5–8 yrs; Cu-IUD 10 yrs)

Replace or removeFertility plans
5
Peri-menopausal transition (age ≥45)

Review whether method still appropriate. IUS (Mirena) can remain until age 55 if fitted ≥45 and provides endometrial protection for HRT. COC can continue to menopause if no CI but switch to HRT at 50–52 for menopausal symptom management. Cu-IUD fitted ≥40 can remain until 1 year post-menopause.

7J — Safety-netting: exact phrases + medico-legal rationale

⚠ Three scenario-specific phrases — use these verbatim

🔴 Emergency — potential pregnancy or ectopic with IUD
"If you get a positive pregnancy test at any point while using the coil, or if you develop one-sided abdominal pain, shoulder tip pain or feel faint, please go straight to A&E — don't wait to call us. This is because, rarely, a pregnancy can start in the tube rather than the womb."
Names ectopic pregnancy as the specific risk; uses non-medical language; gives a clear action (A&E) with named symptoms. Medicolegally essential documentation for IUD users. Failure to warn of ectopic has resulted in inquest findings against GPs.
💊 Medication — missed pills and additional precautions
"If you miss two or more pills in a row, follow the instructions in the packet — you'll need to use condoms as well for 7 days. If you've had unprotected sex in that time, please contact us urgently about emergency contraception."
Specifies the number (2+) and the action (condoms + EC if needed). Prevents the common error of patients using 1 missed pill as the threshold. The "7 days" figure is concrete and actionable.
🟠 Method-specific — DMPA fertility delay counselling
"I want to be clear that after stopping the injection, it can take up to 12 months — sometimes longer — for your normal cycle and fertility to fully return. If you're thinking about a pregnancy in the near future, we should discuss alternative methods today."
Prevents regret and complaint from women who were not warned of fertility delay before starting DMPA. This specific warning must be documented in the notes to be medicolegally protective if a patient later complains of delayed fertility.

Closing the consultation
"To summarise: we've agreed to start [method] today. The important things to watch for are [safety-net symptoms]. Please come back in 3 months for a review."
"Is there anything else about what we've discussed that you'd like me to go over?"
"I want to make sure you're happy with this plan and it feels right for you."
"If anything changes — new symptoms, new medications, or if you change your mind about what you want — please come straight back."
"I'll give you a leaflet about [method] as well — there's a helpline number on there if you have questions between now and your next appointment."
Deductions — closing
  • No summary of plan at end of consultation — loses Tasks and GS marks
  • No safety-netting — missing ectopic warning for IUD is patient safety failure
  • No follow-up arranged — even if patient declines, offer must be documented
  • No closing question ("anything else?") — loses Relating to Others mark
  • No written information offered — NICE recommends written support for all contraception decisions
  • Not documenting BP value / UKMEC assessment — medicolegally incomplete
Tasks domain — full criteria
  • UKMEC assessment completed and documented
  • Most appropriate method recommended with clinical justification
  • EC or bridging method offered where relevant
  • Pregnancy excluded before IUCD/hormonal start
  • Follow-up arranged with specific timeframe
Relating to Others — full criteria
  • Patient's own contraceptive preference elicited and acknowledged
  • Hidden concerns (weight, cancer, fertility) explored and addressed
  • Shared decision making — patient chose method, not examiner
  • Non-judgmental throughout sexual history and risk assessment
  • Reproductive coercion / safeguarding explored if cues present
  • Closing question asked: "Is there anything else you'd like to ask?"
🔴 Red
No UKMEC check • UKMEC 4 method prescribed • no safety-netting • no follow-up • method imposed not chosen • pregnancy not excluded before IUD
🟠 Amber

Complete the checklist above to see your score interpretation and feedback
"Hi, I wanted to talk about the pill. My friend is on it and she really likes it — I just want something reliable."
Who you are

Emma, 28 years old, primary school teacher. You've been with your boyfriend for 6 months and want to start contraception. Currently using condoms. You smoke 5 cigarettes a day but are embarrassed about this and don't volunteer it unless asked. You get migraines about once a month — you sometimes get a visual "zig-zag" before them that lasts about 15 minutes.

Hidden agenda

You're worried about weight gain on the pill — you've heard from friends that it makes you gain weight and you're self-conscious about this. You're also secretly worried it might affect your fertility when you want to try for a baby in 2-3 years. You won't mention these unless the doctor specifically asks about concerns.

Symptoms if asked directly
  • Migraines: once a month, moderate severity; they last 6-8 hours; you get a visual "zigzag" (aura) for 15 minutes before them
  • No personal history of blood clots; no family history (if specifically asked)
  • Last period: 3 weeks ago; regular 28-day cycles
  • No current medications
  • Smoking: 5 cigarettes/day; reluctant to admit this initially
Lifestyle + bonus details
  • BMI approximately 22 (slim build)
  • Drinks alcohol at weekends (8-10 units)
  • Exercises 3x per week; worried any weight gain would affect this
  • Would be open to the implant if explained well — reveal this only if asked about preferences for something she doesn't need to take daily
"But my friend is on the pill and she has migraines too — why can't I have the same thing? Are you saying there's something wrong with me?"

Resolution: Accept the plan if: (1) The doctor explains the migraine aura finding in plain language without alarming language; (2) Offers an alternative that is equally effective (POP or ideally implant); (3) Addresses the weight gain concern with evidence; (4) Acknowledges the fertility question and provides accurate information about return of fertility; and (5) Offers a follow-up appointment.

"Positive pregnancy test or one-sided pain with coil → A&E immediately."
💊 Missed pills
"Miss 2+ pills → condoms 7 days + EC if unprotected sex in gap."
🟠 DMPA fertility delay
"Fertility may take up to 12 months to return after last DMPA injection."
Follow-up timeline
1
3 months (COC/POP): BP, side effects

📌 LARC same-day fitting = 3x higher uptake (NICE)
🔬 5 — Monitoring
MethodWhat to checkTimingAction if abnormal
COCBlood pressureBefore start; 3m; annually≥160/100 = stop COC; switch POP/Cu-IUD
AllBMI / weightAnnuallyBMI >35 = COC UKMEC 4; EC >70kg = UPA/Cu-IUD
IUD/IUSThread check6 weeks; annuallyMissing threads = pelvic USS
DMPABMD; weight; mood>2 years useBMD loss = switch; supplement calcium/vit D
ImplantPalpability3m; annuallyNon-palpable = X-ray/USS

🚫 9 Danger Zones
COC without migraine aura check
→ "Do you get visual changes before headaches?" — UKMEC 4 if yes
No smoking check at age 35+
→ Smoker ≥35 + ≥15/day = absolute COC CI
No pregnancy test before IUCD
→ Must document pregnancy excluded before any IUCD insertion
Missing EC time window
→ Ask EC timing first; 72h LNG / 120h UPA / 5d Cu-IUD
LNG-EC to patient >70kg
→ UPA 30mg or Cu-IUD; LNG significantly less effective
DMPA without fertility delay counselling
→ Document: fertility up to 12 months to return; patient counselled
No ICE explored
→ Always probe ideas, concerns (weight/fertility/cancer) and expectations
No ectopic warning for IUD users
→ "One-sided pain or +ve test with coil → A&E immediately" — document
No Fraser assessment under-16
→ Document Fraser criteria in full; never refuse to a competent under-16
