TTC 1 year - help!

My husband and I have been TTC for about a year now (since July 2015)... I have been getting positive opks monthly. I had been on birth control for 5 years prior to July 2015. My whole life I have been very regular and never went a month without Aunt Flo. In February 2016 I was 10 days late before I got my period. This has never happened to me (being late) so we thought I was pregnant. Since this isn't normal for me I decided to go to the doctor and get checked out. After some blood work she diagnosed me with PCOS. (She said a mild case) I have been on Metformin since February and still no BFP. My husband has an appointment soon to get checked as well. Just wondering if anyone else has been in this same/similar type of situation? Or any other thoughts/advice? Thanks in advance!! :)
