The morning after pill, also known as "Emergency Contraception" is promoted as a quick and easy answer for unprotected sex, but there are some important things you should know before taking the pill. The morning after pill is a large dose of oral contraceptive also known as "Plan B". The pill is actually 2 tablets, one taken within 72 hours of intercourse, and the second pill, 12 hours later.
