Hi, I have PCOS and was on metformin for over a year but it was to control the hormone levels. I was told i would never fall pregnant because my PCOS was so advanced i have had it since i was 11 and i got my first period at 9 and have been in and out of hospitals for years with it. I was only diagnosed february last year by my GP who is brilliant. He told me there was a very slim chance of falling pregnant and he put me on folic acid to reduce the side effects of the metformin. I never actually ever had a `normal` cycle it was not uncommon at all for me to skip 2,3 or 4 periods or to bleed heavily and constantly for up to 10 weeks straight but the metformin and the folic acid quite clearly worked a charm and im now 16 weeks pregnant. It wasnt planned or thought possible but it did happen so there is hope regardless of severity of the disorder.
Have a great day
Mel
