Emergency contraception is a method used after unprotected sexual intercourse or contraceptive failure to reduce the risk of pregnancy. Options include the emergency pill (levonorgestrel or ulipristal acetate) and the copper IUD.
The choice between these options depends on the time elapsed since unprotected sex, the point in the menstrual cycle and body weight. The pill's efficacy decreases with time, while the copper IUD remains effective for up to five days.
Emergency contraception does not protect against sexually transmitted infections. If there is a risk of STIs, the doctor may recommend additional testing. In any case, it is best to consult as soon as possible to choose the most appropriate option for each situation.
