I just found out I am 6 wks pregnant and i have PCOS, I caught pregnant whilst taking metfomin, my doc says I should now stop taking metformin but after a lot of research on the internet, i have found out that most people mainly in america keep taking it as it reduces the risk of miscarriage - which i suffered in Nov 2004 not taking metformin - does anyone have an idea about taking metformin whilst pregnant and what harm it could do if any to the unborn baby???
