Well I know first off that I need to go to the doctor and get the real answer but I was hoping that I could hold out long enough so my health insurance could kick in.. Let me start off by saying I am 21 and I have never had a period last longer than a week maybe two and that includes coming on and off birth control pills and the depo shot... Recently about a month ago my depo shot should have stopped working and about a week before that I started a really heavy period. I have had this period for the past 5 weeks continuously with a rare couple hour break and usually its really heavy. I also am having cramping pain that is so horrible that I cannot function, and I have never had cramping before. Does anyone know what may cause this?
