Emergency contraception (EC), also known as the 'morning-after pill', is a method of preventing pregnancy after unprotected sex or contraceptive failure. EC works primarily by preventing ovulation, fertilization or implantation of an egg in the uterus. It's most effective when taken as soon as possible after intercourse but can still be effective up to five days later. However, its efficacy decreases with time.
