In December I took the Morning-After pill. I haven’t gotten my period since then. Can the Plan B pill mess up your period?


Taking an emergency contraceptive, like Plan B, can change your regular bleeding pattern. The Plan B pill is a dose of progesterone, a natural hormone that builds up the lining of the uterus. The medication is actually tricking your body into thinking it should have a period. You should have some sort of bleeding within three weeks of taking the Plan B pill. If you do not have any bleeding or spotting (minimal bleeding) within three weeks, visit Teen Clinic for a free or low-cost pregnancy test.

You can find more information about your period, Plan B and other birth control methods on our website.  Make an appointment at Teen Clinic for a personalized consult.
