I was diagnosed with PCOS last Dec. Since then my doctor has given me Metformin 500mg to take daily. I did one round of Clomid 50mg last month. No BFP. I was VERY upset because I was so sure I O'd. This month on what would be cycle day 35, AF shows up UNMEDICATED! I'm super stoked. Hopefully this cycle will be the one that gets me a BFP! Going to pick up my Clomid 100mg today.
