I have been taking birth control pills for a month and half. I stopped taking them 4 days ago. I just got off my period the 11th of the month. And now, I have really bad cramps and I started my period. It's lighter than my regular period and more watery. I have never had cramps before or while I am on my period. It doesn't look like my normal period and is almost two weeks early. I don't know what's going on. Yes, I am sexually active, and no we don't use protection.. Any help would really be appreicated. Thanks!
