well I have been on birth control for 8 moths now and my last period was two weeks ago. It was very heavy and seemed exactly like a period I have had before ive taken the pill. Now one week into my active pills I have thought it was just spotting but now it is a heavy blood coming out. It is like a full blown period. I have never had problems on the pill and I try to take it at the same time it varies sometimes 9:30 pm to 11:00 p.m but I try to stay consistent. Mostly ill be taking it at 10:30 and 10:40. I also take it everyday and haven't missed??? Does anyone know what could be wrong??? If it heps I take multivitamins, biotin and vitamin c.
