Emergency contraceptive pill

An emergency contraceptive pill (ECP) is a medication used to prevent pregnancy after unprotected intercourse or contraceptive failure, such as a broken condom. ECPs are most effective when taken as soon as possible, ideally within 72 hours, but some types can be used up to five days later. They work primarily by delaying or inhibiting ovulation, which prevents the sperm from fertilizing an egg. ECPs are safe for most people and do not harm an existing pregnancy. They are available over-the-counter in many places, although availability may vary by location.
