About Emergency Contraception
Emergency contraception is birth control that prevents pregnancy after sex, which is why it is sometimes called “the morning-after” or “day-after” pill. You can use emergency contraception right away—or up to five days after sex—if you think your birth control has failed, you didn’t use contraception, or you were forced to have sex.
Emergency contraception can be 75-89% effective if taken within 72 hours of unprotected intercourse, but it can also be taken up to 120 hours (5 days) after. While it will make it less likely that you will become pregnant, it is not as effective as birth control like the pill or condoms. If you are sexually active or planning to be, don’t use emergency contraception as your only protection against pregnancy. Also, emergency contraception does not protect against sexually transmitted infections like HIV (only condoms do).
