Emergency contraception is a form of birth control that may be used for up to five days after sexual intercourse has taken place. Emergency contraception is often used when no contraceptive methods were used, when the one or more birth control methods used may have failed, or when a woman was made to have sex against her will. The options for emergency contraception are emergency contraceptive pills and the Copper-T Intrauterine Device. These methods are not as effective as primary birth control methods used before or during sex.
