So I'm 24... I have been having my period every 2 weeks and this last time it lasted for 3 weeks, and its still going. I'm on the pill and I take it at the exact time every day. Yesterday was my last active pill for this pack and since your supposed to get your period during the week of the inactive ones, I'm scared this could carry on for another week, meaning I would have my period for a month... or more. I have not had any sexual intercourse this whole time because it is really heavy. What's up?

What's up is that it's time for a visit to the doctor. This pill may not be working for you or there may be something else going on, but only a doctor can tell you for certain.
