I don't have PCOS, but I was not ovulating regularly. I took 50 MG of CLomid and then was on estradiol supplements to increase my uterine lining as it was way too thin.
I too suffer from PCOS...the cause of my amenorrhea was due to a lack of ovulation...I am currently on clomid 100mg and 1500mg of metformin...I'm praying this is my cycle!!
An ovidrill shot made me ovulate. I have pcos so have never ovulated until the shot. Now I'm 6 weeks pregnant :o)
