What is the efficacy of taking the emergency contraceptive pill Unwanted 72 approximately 36 hours after unprotected intercourse involving withdrawal, and what are the potential hormonal side effects?
Taking Unwanted 72 (levonorgestrel) 36 hours after intercourse is still highly effective at preventing pregnancy, especially since withdrawal was also used. Regarding side effects, it is very common to experience mild, temporary hormonal symptoms like mild nausea, headache, fatigue, or breast tenderness. Your next period might also be slightly early, late, or vary in flow. These fluctuations are normal and should resolve soon. If your period is delayed by more than a week, a home pregnancy test can be performed.
