Dealing with PCOS.

I was recently diagnosed with PCOS. I was on birth control since I was 17, I got married 1 year ago, and we decided to get off the pill in June, August came around and I still had no period, worried I went to my gyn, and she started me on progesterone, which gave me my cycle, but It wasn't every month, and I would have extreme cramping with no period. I was sent for a abdominal US and it showed cyst, she had me go back in 3 months. At my 3 month US it showed no cyst.  So at my January appointment I still only had my period twice. She made me take a pregnancy test, even after I told her I took them and they were all negative. (It upsets me to see a negative). When I was negative, she said "well you need to have your period to get pregnant.... But the meds she put me on is only an every 3 month thing. . So I decided to go see my family dr. After reviewing the US and my blood work. He diagnosed me with PCOd, and started me on Metformin.... Is anyone here dealing with PCOS. And taking Metformin?
