My husband and I have been ttc for 6 months with PCOS. Ive been on letrozole, metformin, baby aspirin, vitamin b 12 and b6 and I take progesterone after ovulation. We had two early chemical pregnancies and then this month I went gluten free, also used Preseed as well as the digital ovulation tests. this cycle we also changed some things up because my ovulation was starting to get too late in my cycle and my doctor doubled my letrozole dose this cycle ... and it seemed to work! My period is due on my birthday and it looks like this will be the best birthday ever! 9 dpo bfp. Just wanted to share in case it helps someone else!
