Just to update everyone on my situation, I was taking prometrium 400mgs, 2nd try..(first try was 200mgs). I took the meds for the time frame of Dec. 3-Dec. 14. Today I have finally started my period. WOOO HOOOOO!!!!! It's been more than two years. Anywho, my gyn wants to put me on clomid. Does anyone have any advice for me while taking Clomid? what are your experiences with it, is it successful, how long can I take it, will it help? wow....too many questions. Thanks again!
