Short answer
Post-exposure action runs on three clocks simultaneously: HIV PEP within hours (evaluation immediately, first doses within 72. Sooner substantially better), emergency contraception within days (oral options within 3–5 days by type, copper IUD to 5 days), and bacterial STI testing now plus retests (baseline immediately, window-dated follow-ups over weeks).
Move on all three in parallel, abstain meanwhile, and loop partners into care now rather than after results.
Anxiety-driven same-day action beats Monday-morning regrets in every comparison.

See Tests & Prices →First hour: triage. Three questions in order
Was HIV exposure possible? (condomless anal or vaginal sex with unknown-status partner, shared injection equipment, sexual assault, known-positive partner with unsuppressed load → PEP evaluation now at an ER, urgent care, or sexual-health clinic. Starter packs carried around the clock.) Contraception risk? (pregnancy possible → emergency contraception options within 5 days, with copper IUD most effective and doubling as ongoing contraception.) Safety threat? (coercion, violence, assault → support services, forensic options, and safety planning first. Medical and legal pathways run in parallel.) Answer all three within the hour; each has its own clock and none waits for the others.
First days: baseline testing. Document, then watch
- NAAT plus HIV/syphilis/hepatitis blood work establishes baselines and catches pre-existing infections (older exposures surfacing now. Treatable immediately rather than attributed to the new event).
- Some clinicians presumptively treat high-probability bacterial exposures. Follow their judgment over internet protocols (presumptive therapy decisions weigh exposure type, partner status, and follow-up reliability).
- Pregnancy testing where relevant (timing subsequent contraception and retesting).
Baselines serve the future: without them, later positives cannot be dated to this exposure or earlier ones.
Window logic at STI Testing Window Periods Explained.
Coming weeks: retests. Dated, calendared, kept
- Return after each relevant window closes: bacterial NAAT in 1–2 weeks, HIV/syphilis blood work at 6 weeks and 3 months per situation and test generation.
- Abstain or use condoms strictly until cleared (the protocol’s protection runs through the last retest, not the first negative).
- Notify partners of possible exposure now, results later (their PEP and testing windows open immediately. Waiting for your results wastes their hours).
Calendar every date before leaving the clinic; intentions without dates evaporate under anxiety.
Emotional steadiness. Scheduled actions beating rumination
Post-exposure anxiety is normal and peaks during waiting. Uncertainty plus stigma plus imagination.
- Scheduled actions beat rumination: kept appointments, written timelines, partner drafts prepared, sleep and movement protected.
- Avoid symptom-search spirals (hypervigilance manufactures symptoms hourly. Scheduled check-ins with trusted sources instead).
- Use clinician counseling over forums (personalized risk assessment versus anecdote compilations).

When to seek care
Immediately for PEP assessment, within days for baseline testing and contraception, on schedule for retests. And urgently for symptoms, assault, or safety concerns.
