Non Diabetic/PCOS use of Metformin for TTC and weightloss.

Hi! I was prescribed 2000mg a day of Metformin for weight loss(working up to that to build tolerance to gastrointestinal side effects). I am also TTC so my doctor said the side effect of increased pregnancy is just in my favor. I am hoping there is someone on here who is or has taken metformin and who isn't diabetic or pcos. I really want to know what other ladies have experienced :). Thank you!!!
