I've been having heavy bleeding problems from the time I was 12 up until now, and I'm 31.I've always had heavy clotting, no answers from doctors. I've always been on the heavy side. My periods were always very irregular, so I was on birth control from ages 12-22. I haven't been able to have children, never been told I couldn't from a doctor. I have lost 30 pounds and now all of a sudden I'm having what seems like to be normal periods, ranging 5-6 days. Could this be due to weight loss?
