The Morning After: This pill is very effective. It can throw off the menstrual cycle in minor ways. If you do not get your period and want to be certain then that is the time to get a home pregnancy test.

Emergency: contraception is up to 89 % effective when taken within 72 hours (3 days) after unprotected sex. It can reduce chance of pregnancy by up to 95% if used within 24 hours. It continues to reduce the risk of pregnancy up to 120 hours (5 days) after unprotected sex, but is less effective as time passes.
