Ive been goin through so much testing for fertility, and what it seems like is i have Pcos... im put on metformin for now, so what im askin is what is the best vitamin/fertility booster to order off amazon? Any one taking anythin that might be good for me to take? ( i have veryyy regular periods) so i wanted to see if i can find just a good booster or good vitamin other than folic acid
