What is emergency contraception?Emergency contraception is used after sex, rather than before, to prevent pregnancy. In the event that regular contraception fails, or if voluntary or involuntary unprotected sex, emergency contraception provides up to five days in which to potentially prevent pregnancy.
What are the different types of emergency contraception?
Most emergency contraception is hormonal. The simplest method of emergency contraception is to combine birth control pills containing the hormones progestin and estrogen in each of two doses, taken twelve hours apart. Only some versions of the pill are effective for this, and only at specific doses.
