Methods: A retrospective chart review of 49 patients who reported 8 or more days of bleeding
was performed. They were then divided into three groups based on endometrial thickness (mm):
less than 6, 6–11, and greater than 11. These three groups were treated with combined oral
contraceptive pills (OCP), conjugated estrogen plus progesterone and megestrol respectively.
Patients given megestrol also underwent endometrial biopsy before treatment. Patients recorded
the degree of bleeding each day for one month after starting treatment.
