Medroxyprogesterone

My RE has me taking it twice a day for three months to treat complex endometrial hyperplasia without atypia, with the hope we can do our last two rounds of Clomid after a clear biopsy sometime starting in August. Cycle day 21 of month two...I. Am. Miserable. Has anyone else been through this? Will the bleeding ever stop? At this point I would be thrilled for it to slow to spotting...guh.
