I was diagnosed with PCOS. They tried me on I think it was clomid, which didn't help. I miscarried in 2008. Was given metformin which I concieved successfully after a few months of being on it. And my daughter is now 21 months old.
I never really had periods and when I did it was one or two a year if I was lucky.
I agree with what others have said on here, its good to go on it even if its just to help your ovulation or health.
Wish you all who are in same boat the best and sending lots of baby dust your way.
I managed to get my baby after a long wait. But she is finally here now and with a new little precious on his/her way xx
