So, i started Birth control again after about a year of not being on it. My doctor told me to start taking it as soon as my period started, and thus i did. Then, my period lasted 2 WEEKS.... i was off my period for 10 days and now its starting up again. I KNOW this isnt normal. Can someone help tell me whats wrong? The last time i was on BC, this didnt happen at all. I was also on a different brand than the current. Would that have anything to do with it? Someone please help, should i go to my doctor about this?
