what to do after unprotected sex

If you’ve had unprotected sex, the most important things are acting quickly to reduce the risk of pregnancy and checking for sexually transmitted infections (STIs). Here’s what to do, step‑by‑step, in plain language.

🚨 First few minutes (right after)

  • Go to the bathroom and pee soon after sex to help wash out bacteria that can cause urinary‑tract infections (UTIs). This is especially helpful for people with vaginas.
  • Wash the outside of your genitals with warm water and mild soap if you want, but do not douche (no special “cleansing” inside the vagina or anus). Douching can irritate tissues and raise infection risk.

🕒 Within 72 hours – avoid pregnancy

Time matters a lot if you’re trying to prevent pregnancy.

  • Emergency contraception (EC) “morning‑after pill” :
    • Pills like levonorgestrel (e.g., Plan B, Postinor‑2) work best if taken within 24 hours , but can still help up to 72 hours (3 days) after unprotected sex.
* Another option, **ulipristal acetate (Ella)** , can be taken up to **120 hours (5 days)** and is more effective than standard “Plan B”‑type pills, though it usually needs a prescription in many countries.
  • Copper IUD (emergency backup) :
    • A copper‑bearing IUD inserted by a clinician can be placed up to 5 days after unprotected sex and is one of the most effective emergency methods , often over 99% effective.
* It also doubles as long‑term birth control for many years.

💡 Note: Emergency contraception prevents pregnancy by delaying ovulation or making it harder for sperm to reach an egg; it does not end an existing pregnancy or cause abortion.

🕓 Within 72 hours – HIV exposure concern

If there’s a chance you were exposed to HIV (for example, a partner is known‑positive or status‑unknown and you had anal or vaginal sex without a condom):

  • Post‑exposure prophylaxis (PEP) can reduce the risk of HIV infection if started as soon as possible , ideally within a few hours and no later than 72 hours after exposure.
  • PEP is a course of HIV medicines taken for about 28 days and must be prescribed by a doctor or sexual‑health clinic.

🧪 Within 2 weeks – STI testing

Even if you feel fine, some STIs don’t show symptoms right away.

  • Consider getting tested for HIV, chlamydia, gonorrhea, syphilis, and other STIs about 2 weeks after unprotected sex , especially with a new or status‑unknown partner.
  • Common warning signs that should prompt immediate medical care include:
    • Burning or pain when peeing
    • Unusual or smelly discharge from the penis or vagina
    • Sores, blisters, or unusual bumps around the genitals or mouth
    • Unexplained bleeding or rash

Testing can be done at clinics, sexual‑health centers, or via telehealth services, depending on your country.

🤰 Within 2–3 weeks – pregnancy test

  • Take a home pregnancy test about 2–3 weeks after unprotected sex or on the day of your missed period , whichever comes first.
  • Early tests look for the hormone hCG , which often isn’t high enough to detect if you test too soon.

If the test is positive, contact a healthcare provider or clinic to discuss options (continuing the pregnancy, abortion services, counseling, etc.), since laws and support vary by location.

🔁 Moving forward – safer sex

Once the immediate steps are done, think about how to protect yourself next time:

  • Barrier methods : Use condoms (male or female) every time for oral, vaginal, or anal sex.
  • Regular birth control : Combine condoms with a long‑acting method (IUD, implant, shot, or daily pill) for much stronger pregnancy protection.
  • Routine STI screening : Especially if you change partners or have new partners, regular testing helps catch infections early.

If you tell a bit more about your situation (e.g., where you’re located, whether hormones/IUDs are easily accessible, or if it was a one‑time vs regular partner), tailored advice can help you narrow down which step is most urgent for you right now.
