Despite its name, the morning-after pill doesn't have to be taken in the morning. Emergency contraception can be taken at any time of day, but effectiveness decreases with delay. For best results, take it as soon as possible after unprotected sex—ideally within 72 hours, though some types work up to 120 hours (5 days) later.

If you're unsure about your situation, experiencing unusual symptoms, or worried about side effects after taking emergency contraception, getting clarity quickly matters. A free, instant, online symptom check can help you understand what your body is telling you and guide your next steps—whether that's monitoring at home, seeing a doctor, or ruling out other concerns. It takes just a few minutes and could save you hours of worry.
