Problems with Yaz!?!?

Yaz is not THE cure. Any birth control pill will likely help you, though higher dose is better. So you can very easily change to a different birth control pill that will hopefully not come with the same mood swings. Talk with your doctor and you can start experimenting. Also, being on birth control pills won't cause you to not be infertile. It treats the symptoms of PCOS but doesn't cure it. And you can't get pregnant while taking the pill, of course. Something that might help is Metformin, which addresses some of the problems of PCOS. Many women with PCOS find that they become fertile when they take Metformin.
