Plan B: The morning after pill (brand name Plan B) can be taken up to 72 hours after unprotected sex. It is most effective when taken as soon as possible following the time of unprotected sex. Most recommend that you wait until the first day of your missed period before taking a home pregnancy test. As you may know, a missed period is usually one of the first signs of pregnancy.
