Unprotected sex happens. What matters most is what you do next. The first 72 hours are critical — especially if HIV exposure is a concern. This article walks through exactly what to do, in the right order.
If there is any chance of HIV exposure, this is the most urgent step. PEP (Post-Exposure Prophylaxis) is emergency HIV medication that must be started within 72 hours of exposure. The sooner you start, the more effective it is.
Do not wait to see if symptoms appear. Do not wait until Monday. Contact a clinic immediately.
Same-day consultation available · Open daily 8am–10:30pm
Ask a Doctor NowIf HIV is not a concern, you can take a breath. But you should still get tested — and timing matters.
The window period is the gap between infection and when a test can accurately detect it. Testing too early can give a false negative — even if you are genuinely infected.
| STD | Window period | When to test |
|---|---|---|
| HIV | 18–45 days (4th gen test) | At least 3 weeks after exposure; retest at 45 days |
| Chlamydia | 1–2 weeks | 2 weeks after exposure |
| Gonorrhoea | 1–2 weeks | 2 weeks after exposure |
| Syphilis | 3–6 weeks | 6 weeks after exposure for reliable result |
| Herpes | 4–6 weeks | 4 weeks or when symptoms appear |
| Hepatitis B | 6 weeks | 6 weeks after exposure |
If you are unsure when to test, your doctor at Mediprima TTDI can advise based on your specific situation and exposure type.
A full STD panel is recommended after any unprotected sexual encounter. At Mediprima TTDI, this covers:

A positive result is not the end. Most STDs are very treatable, and even HIV is manageable with the right medication.
Chlamydia, gonorrhoea, syphilis — fully curable with a short course of antibiotics.
Not curable but highly manageable. With treatment, people with HIV live long, healthy lives and can reduce transmission risk to near zero.
Not curable but outbreaks can be controlled with antiviral medication.
Most infections clear on their own. Warts and abnormal cells are treatable.
You should also inform any recent partners so they can get tested. Your doctor can advise how to approach this sensitively.
Wait at least 2 weeks for most STDs. For HIV, a 4th generation test is reliable from 18 to 45 days. Testing too early may give a false negative.
Yes. PEP is available at private clinics including Mediprima TTDI. It must be started within 72 hours of possible HIV exposure. WhatsApp 010-2688219 for same-day consultation.
Not always, but the risk is real. Many STDs show no symptoms, so you cannot know your status without testing. One unprotected encounter is enough to transmit an infection.
You can visit the clinic the same day for advice and PEP if needed. However, STD tests are most accurate after the window period — at least 2 weeks after exposure for most infections.
