I was on Metformin for insulin resistance w/ PCOS. I didn't have any side affects with it at all. If you are over weight, that can be causing your problem with conceiving, & losing weight will really help your chances of getting pregnant. Being 41, I wasn't looking to get pregnant at all, but after losing a lot of weight, I found myself unexpectedly pregnant! About 6 mos after having my son, I found myself pregnant again! Of our 4 children, 3 of them are "weight loss babies".
