  1. Morning-after pill

    Plan B, also called the morning-after pill, is an emergency contraceptive pill taken after unprotected sex to prevent pregnancy. You don't, however, have to wait until the morning after sex to take it. It contains the hormone levonorgestrel, which is more effective the sooner you take it.
