I was diagnosed with PCOS when I was 18 in 2008 due to irregular/ no menstrual cycles. I went on birth control to regulate the cycles ! In January 2013 DH and I decided we wanted to ttc. I got off bc and had no cycles at all ! My OB decided to put me on metformin to regulate the cycles. I started at 500mg and gradually worked my way up to 2000mg which regulated the cycle but I was still unable to conceive. After 1yr of ttc without success my OB decided to add clomid in September 2014 I started with 50mg cycle days 3-7 at 7dpo my progesterone was 5.2 which was not significant of an ovulation! They like it to be over 10 So my dose of clomid was increased to 100mg cycle days 3-7 at 8dpo my progesterone was 23.4 yay! On day 34 of the cycle I decided to take a pregnancy test and after 4 BFP's I am pregnant my due date is July 21 2015
