The best advice I can give you is to stay on the metformin. I read a study that said 48% of women with PCOS who didn't take metformin for at least their first trimester ended up having a m/c. But, for those who stayed on the met they had a normal m/c rate of 12%. So, stay on the met and try to reduce your stress and you, too, will probably have a healthy baby

Good luck and sticky baby dust***!
