I had the same thing happen, and it never resolved itself. My OB tried BC pills, hormone supplements and D&C's (2 of them). Nothing worked. This went on for 3 years. I had a hysterectomy in '09. I hope it doesn't happen to you this way, but if it goes on for another cycle, I would see a doctor. I could be polyps, hormones, or who knows what? Good luck.
