After i stoped taking birth control i had a few irregular periods it could be because of that.if you are bleeding very heavy it could be a miscarage or just an irregular period caused by you ending the birth control .i was bleeding heavy this month and i wasnt suppose to start for like 18 days because i had just had my period i went to the doctor and they tested me for serum pregnancy (to see if i miscaried) everything came back ok for me sometimes are menstrual cycles are unpredictable lol but if u are bleeding very heavy you probably are not pregnant go to your doctor to knoe for sure whats going on
