Okay so I'm 18 and just started using birth control. For the obvious reason of contraceptive but also to help ease my crippling period cramps. I was put on lo-loestrin fe by a doctor as a low dosage. I know that the pill messes up your flow but y'all..... this messed me up big time. I was supposed to get my period two days before IS started my pill. It came late, which didn't shake me at ALL because I have a really irregular flow. But Lors this thing pushed me back 3 WEEKS. But that isn't my promblem. My issue is that I got my period on the 7th of November and today, on the 16th the blood is still flowing. Is this normal or should I go back to the doctor for a follow up? Pls help!
