I'm 40 yrs old. History of PCOS, Abnormal paps leading to Leep Procedure last year. Clomid was prescribed for my 2 normal pregnancies. My periods have been regular since being on Glucophage XR for the PCOS for about 5 years now. regular upto this month. About 4 days before my period was due, I had a thick dark brown discharge. I only bleed for about one day. It was bright red, not pink, no clots. 2 days passed. Bleed for only about 1/2 day after that. Nothing since. I am having some discomfort during sexual intercourse. This has been since the LEEP procedure and only happens everyonce in awhile. (My OBGYN advised me there is some scar tissue)I have taken 3 pregnancy tests, all negative. Is this the start of premenopause? I did not really have a period this month, or was that my period?
