Ann, if I remember correctly, I may have had a week to 10 days off, then a heavy period would start tapering off to a month of light bleeding and spotting. It was awful. I was checked out by ultrasound and endometrial biopsy and everything was fine. I did become anemic. I would say even if your ferretin is good now, pay attention to your foods and try to eat iron-rich. They did offer me an ablation, but since they presumed the problem to be peri, I declined to go through with that. Eventually I was given a prescription for transexamic acid to stop heavy bleeding, but by that point I was missing my periods and when they would come along they were short and light. So there is an end to that part eventually!
