!
Pregnancy, sepsis or assault emergency

Collapse or severe abdominal pain with pregnancy possibility, pelvic pain with systemic illness, acute sexual assault, genital injury or imminent exploitation requires same-day emergency and safeguarding coordination.

Action: Stabilise medical needs, use the local ectopic pregnancy, pelvic infection or sexual-assault pathway, preserve forensic options without withholding urgent care, provide time-sensitive emergency contraception or prophylaxis when indicated, and involve safeguarding expertise proportionately.

Role and principles

Provide confidential, non-judgemental contraception and sexually transmitted infection care for young people, exclude urgent pregnancy or infection complications, assess competence and coercion, choose effective methods with current eligibility guidance, and secure treatment, partner and safeguarding follow-through.

Young people should be able to access respectful sexual-health care without assumptions about identity, behaviour or parental support. Begin privately, outline confidentiality and ask what outcome matters today. Assess decision-specific competence and whether sexual activity is consensual. For someone under 16 seeking contraception, explore understanding of advice, likely continuation of sexual activity, ability to involve a parent or trusted adult and physical or mental welfare; these Fraser considerations support care but do not replace a full safeguarding assessment. Age alone, a partner's age alone or a single checklist cannot settle safety.

Contraceptive choice is shared and non-directive. Explain typical-use effectiveness, duration, bleeding changes, privacy, procedure, reversibility, effect on acne or pain, interactions and practical access. Intrauterine contraception and the implant offer high effectiveness without daily action, but declining them must not become a barrier to pills, injection, condoms or continued counselling. Apply current UKMEC to migraine with aura, thrombosis risk, hypertension, medicines, liver disease, postpartum state and other relevant conditions. Check blood pressure before combined hormonal contraception and body mass index where it changes eligibility; intimate examination is not required for most non-intrauterine methods.

Assessment and patient selection

Contraceptive priority

The young person identifies the relative importance of effectiveness, bleeding control, privacy, daily action, procedure avoidance and rapid return to fertility.

Possible pelvic inflammatory disease

Lower abdominal pain, deep dyspareunia, abnormal bleeding or discharge with pelvic tenderness raises concern and treatment should not await every result.

Possible exploitation

Pressure, fear, a power imbalance, gifts, accommodation, drugs, threats, online control or inability to negotiate condoms indicates a safeguarding need.

Method complication

New severe neurological, chest, leg or abdominal symptoms, pregnancy concern, missing intrauterine threads or significant infection symptoms require targeted urgent review.

Need for HIV prevention

Recent high-risk exposure, ongoing partner risk or repeated emergency presentations should trigger timely PEP or PrEP pathway assessment and baseline testing.

Red flags requiring action

  • Pain, shoulder-tip symptoms, bleeding, syncope or shock with pregnancy possibility requires urgent ectopic-pregnancy assessment regardless of reported contraception.
  • Fever, lower abdominal pain, cervical or adnexal tenderness, vomiting or pregnancy can indicate complicated pelvic infection needing urgent specialist care.
  • A large age or power imbalance, threats, inability to refuse, exchanged goods, intoxication, image-based abuse or controlling communications may indicate exploitation or assault.

Baseline assessment

  1. 01
    Pregnancy testingFirst step
    Why
    Identify current pregnancy before decisions where the result changes management.
    Interpretation and limitations
    Interpret against last unprotected intercourse and expected bleeding; an early negative result needs a planned repeat and does not exclude ectopic pregnancy when pain or collapse is present.
  2. 02
    Exposure-directed NAAT
    Why
    Detect chlamydia and gonorrhoea at anatomical sites at risk.
    Interpretation and limitations
    Select urine or genital, rectal and pharyngeal samples by exposure and symptoms; positive gonorrhoea needs culture for susceptibility where obtainable before antibiotics.
  3. 03
    HIV syphilis and hepatitis serology
    Why
    Identify blood-borne and systemic sexually transmitted infection where indicated.
    Interpretation and limitations
    Use exposure timing and window periods, arrange repeat testing where needed, and do not delay time-critical HIV PEP or hepatitis prophylaxis while awaiting baseline results.
  4. 04
    Contraceptive eligibility assessment
    Why
    Identify conditions and interactions that change method safety or effectiveness.
    Interpretation and limitations
    History, blood pressure for combined methods and selected examination or laboratory findings are applied to current UKMEC; routine thrombophilia or pelvic testing is not required for everyone.

Interventions

01Same dayAddress urgent riskFirst stepThere is acute pain, pregnancy complication, sepsis, assault, HIV exposure or immediate exploitation concern.+
  1. 1Stabilise medical needs and activate the relevant emergency, sexual-assault, HIV PEP or safeguarding pathway without avoidable delay.
  2. 2Explain confidential information sharing and preserve forensic choices while prioritising consented treatment and prevention of further harm.
  3. 3Offer time-critical emergency contraception, infection prophylaxis, vaccination or baseline testing when clinically indicated.
  4. 4Name the team responsible for results, follow-up, safety contact and partner or public-health actions.
02ContraceptionChoose and start safelyThe young person wants pregnancy prevention or menstrual benefit and no emergency precludes routine choice.+
  1. 1Clarify priorities and compare all suitable methods using current UKMEC, effectiveness, bleeding, interactions, procedure and privacy.

Medicines and treatment safety

Oral emergency contraception when an intrauterine device is declined, unsuitable or not immediately available.

Levonorgestrel emergency contraception

Give 1.5 mg orally as soon as possible within the licensed interval after unprotected intercourse, applying current FSRH advice for timing, body weight, enzyme-inducing medicines and repeat dosing after vomiting.

Confirm interaction and weight guidance, explain that later intercourse is not covered, provide immediate ongoing-method advice and a timed pregnancy test, and refer pain or abnormal bleeding urgently.

Oral emergency contraception with effectiveness later in the eligible post-intercourse interval.

Ulipristal acetate

Give 30 mg orally as soon as possible and up to 120 hours after unprotected intercourse when suitable; delay starting or restarting progestogen-containing contraception for five days and use barrier precautions as advised.

Review severe asthma treated with oral glucocorticoids, breastfeeding advice, enzyme inducers and recent progestogen exposure; explain the five-day hormonal-method delay and arrange a pregnancy test.

Targets, monitoring and follow-up

  • Confirm the young person can use the chosen method, knows missed or delayed-dose actions and can access repeat supply or procedure appointments confidentially.
  • After emergency contraception, document the ongoing method plan and pregnancy-test date, and review urgently for severe pain, syncope or abnormal bleeding.
  • Track STI results to successful communication, treatment and partner notification; arrange test of cure or repeat screening according to organism and risk.
  • Recheck blood pressure and relevant symptoms for combined hormonal contraception according to local and FSRH follow-up arrangements.
  • Review bleeding, pain, mood, method acceptability and new medicines without removing an effective method solely for expected early bleeding changes unless the young person wants removal.
  • Revisit coercion, online harm, age and power imbalance, housing and safety when presentations recur or the history changes.

Special situations

Offer does not mean pressure

Long-acting methods should be available and explained, but reproductive autonomy includes choosing, declining or removing a method without punitive barriers.

Site matters in infection testing

A negative urine sample cannot exclude pharyngeal or rectal infection after exposure at those sites.

Condoms have a distinct role

They reduce infection transmission even when another method provides much stronger pregnancy prevention, so dual-method discussion remains useful.

Results need a safe route

Before sampling, agree whether a voicemail, text, portal notification or clinic name could expose the young person or trigger harm.

Repeat presentations carry information

Frequent emergency contraception or infection does not justify judgement; it prompts method-access, coercion, partner, HIV prevention and safeguarding review.

Common pitfalls

  1. 01

    Requiring parental permission automatically before offering a competent young person contraception or STI testing.

  2. 02

    Offering only long-acting contraception or making STI care conditional on accepting a contraceptive method.

  3. 03

    Testing urine alone despite oral or anal exposure and then providing false reassurance about infection at other sites.

  4. 04

    Giving oral emergency contraception without explaining ongoing contraception, later intercourse, vomiting and the pregnancy-test date.

  5. 05

    Treating an STI but failing to communicate the result, arrange partner notification or address reinfection and safeguarding.

  6. 06

    Assuming reported condom use excludes pregnancy, infection, coercion or a method failure requiring assessment.

Authoring stateComplete draft

Emergency contraception is time dependent. A copper intrauterine device is the most effective method and can provide ongoing contraception when inserted within the eligible interval after unprotected intercourse or estimated ovulation. Ulipristal acetate and levonorgestrel are oral alternatives selected according to timing and individual factors. Hormonal contraception start or restart timing differs after ulipristal because immediate progestogen can reduce its effect; provide condoms or abstinence advice and a pregnancy-test date. Oral emergency contraception does not protect later intercourse in the same cycle.

STI testing follows anatomy, exposure and time. Chlamydia and gonorrhoea NAAT samples may include urine or self-taken vaginal, rectal and pharyngeal specimens; blood tests assess HIV, syphilis and hepatitis when indicated. Explain window periods and that a test from one site does not exclude infection elsewhere. Symptoms such as pelvic pain, testicular pain, ulcers or systemic illness require examination and urgent pathways. Vaccination, including HPV and hepatitis B for eligible risk groups, and HIV pre-exposure or post-exposure prophylaxis assessment are part of prevention, not optional extras after testing.

Close the loop. Agree how results can safely be communicated, whether messages may name the clinic, and what happens if contact fails. Treat under the current guideline and check allergy, pregnancy and interactions. Partner notification can be patient-led or supported by the sexual-health service without disclosing the index patient unnecessarily. Arrange retesting when recommended, complete vaccination, review contraception after emergency use and revisit safety because disclosure of coercion may occur only after rapport develops.

Key points

  • Offer routine private time, explain confidentiality limits and assess competence, consent, coercion, exploitation and immediate safety without making access depend on parental attendance.
  • Take a behaviour- and anatomy-based history covering last exposure, sites, condoms, contraception, pregnancy possibility, symptoms, partners, vaccination, previous infection and antimicrobial allergies.
  • Use current UK Medical Eligibility Criteria and the young person's priorities to compare effectiveness, bleeding, privacy, reversibility, procedure, interactions and return to fertility.
  • Long-acting reversible methods are highly effective and should be offered without pressure; condoms remain important for STI risk even when another contraceptive method is used.
  • After unprotected intercourse, offer the copper intrauterine device as the most effective emergency contraception when suitable, or an oral method matched to timing, interactions, weight guidance and ongoing-method plan.
  • Select NAAT and serology by anatomical exposure and window period; self-sampling can improve access, but symptoms or assault may require examination and clinician sampling.
  • Treat confirmed or strongly suspected infection under current BASHH or local sexual-health protocols, arrange partner notification and retesting, and record who will communicate every result.
  • Recent high-risk HIV exposure requires immediate specialist assessment because post-exposure prophylaxis is time critical and should not await routine test results.
  • Severe headache or neurological symptoms, chest pain, unilateral leg swelling or breathlessness during combined hormonal contraception requires urgent thrombotic assessment.
