What to Do After Unprotected Sex: Five Practical Next Steps

1. Take a Breath and Check What Happened

First, try not to panic. “Unprotected sex” can mean sex without a condom, a condom that broke or slipped, or missed birth control. Think about when it happened, whether ejaculation occurred, and which types of sex took place. These details can help a healthcare professional recommend the right next steps. If the sex was not fully consensual, or you felt pressured or unsafe, seek immediate support from a trusted person, sexual assault service, or emergency department. Your safety comes first.

2. Consider Emergency Contraception

If pregnancy is possible, emergency contraception may help. A levonorgestrel morning-after pill works best as soon as possible, usually within 72 hours. Ulipristal acetate can work for up to five days and may be more effective later in that window, but it can interact with regular hormonal contraception. A copper intrauterine device, fitted by a qualified clinician, is another highly effective option within five days and provides ongoing contraception. Ask a pharmacist or healthcare provider which choice is suitable for you, especially if you take medication or have health conditions.

3. Ask About HIV PEP and Other STI Care

If there may have been exposure to HIV, contact an emergency department, sexual health clinic, or doctor immediately. HIV post-exposure prophylaxis, commonly called PEP, must be started within 72 hours and works best when started as soon as possible. A clinician can also discuss testing or preventive treatment for other sexually transmitted infections, including chlamydia, gonorrhea, syphilis, and hepatitis. Do not wait for symptoms: many infections cause none.

4. Arrange Testing and Watch for Symptoms

Testing too early can sometimes miss an infection, so ask a clinic when to test based on the timing and type of contact. You may need more than one test over several weeks. Seek medical advice sooner if you notice unusual discharge, sores, a rash, burning when urinating, pelvic or testicular pain, fever, or bleeding. Until you have medical guidance, use condoms or pause sexual activity to reduce the chance of passing an infection to someone else.

5. Take a Pregnancy Test and Plan Ahead

If pregnancy is possible, take a home pregnancy test when your period is late or about three weeks after the sexual encounter. A negative result taken very early may not be reliable, so repeat it if your period does not arrive. If it is positive, contact a healthcare professional to discuss your options and care. Finally, consider what protection would make you feel comfortable next time, such as condoms, regular contraception, or routine STI screening. Getting help promptly is the most important step, and healthcare providers are there to support you without judgment.
