I have pretty bad pcos and take 1500 mg of metformin for the insulin resistance and it also helps with the pcos symptoms. I had the surgery a few years ago and my periods returned from maybe 2-3 a year to about every 5-6 weeks. Yah!!! I have had 5 pregnancies since my surgery and 4 of them didn't make it due to 2 bad eggs, one bad embryo, and a chemical. I will be 40 on uly 20th and my Little girl is due July 19th. Never give up hope!!! I could never get pregnant before the surgery and we have been trying for 18yrs all together. My best advice is that if you are currently on metformin and due become pregnant down the road, stay on it!!! I believe that is why I lost my one embryo a couple of years ago. A fellow member on this board sent me info about pcos, metformin and pregnancy and with this pregnancy I stayed on my metformin (with my ob's permission, he really didn't have a say, I said I was staying on it until month 8)and have a healthy baby girl on her way. Congrats on your surgery and Best of Luck in the future and I hope your dreams come true Like mine are.
