Yes! My dh and I had been ttc for almost 3 years. Six months ago we started seeing a new doctor. Although I didn't exhibit any physical signs of PCOS, my LH was 3X my FSH, and so she diagnosed me. About a month ago, I had an u/s which indicated the little cysts on my right ovary. So she put me on metformin, and I conceived that month. It was truly a miracle. I had the flu right before ovulation, and had a hard time taking my full doses. But, I am 6 weeks pregnant, and I believe the metformin helped. I am continuing on the metformin thru my pregnancy as it can prevent gestational diabetes. Good luck to you!
