TTC with PCOS and on Metformin

Elaina • Mother of 4 living children,2are my husbands,1 is mine and we finally had 1 together. When i was 18 i miscarried a child and 1/23/2015 our son was born sleeping

This past Friday I was told I have PCOS and I started taking metformin. I am on cycle day 45 now. I guess my question is do any of you ladies get the real bad side effects my doctor told me about and can any of you share maybe previous success pregnancy stories that have been in this situation?
