I've been on the pill for about year now due to problems with my cycle. In the past few months those problems have come back even worse. My periods last for up to three months at a time, I bleed through pads in about 30 sometimes 15 minutes frequently, I have severe cramping and back pain and vomiting for the length of my peroid. I also have severe and regular cramping when i'm not on my peroid. But my biggest problem is that my ob/gyn brushes it off as normal and "exaggrating". My question is- Is this really normal? Am I overreacting? I'm only 17 and am very unsure about everything.
