PCOS seems to treat every PCOS woman differently. Some women with PCOS have infertility problems and others have no problem at all having babies. Some women ovulate, some women need help ovulating properly to become pregnant.
I suggest getting the book Taking Charge of Your Fertility. It will help you understand your cycles, track your cycles and by recording this information it will give your dr a better idea of what is going on.
There is a lot that can be done now days in regards to infertility so PCOS is not a diagnosis of infertility
Good luck.
