Success Stories?

I was diagnosed with PCOS about 5 months ago so my periods are wacky. Well I did a round of Clomid last month and didn't ovulate. Then this month no periods and BFN, so my dr has me taking Provera for 10 days then once I get my period starting Clomid again. He also started me on Metformin last month after not ovulating. Has anyone had success taking those 2 meds?
