Good luck n2l. I managed to lose 5kg in 3 months without changing anything. Metformin also helped shorten my cycles and I got a BFP after the 3rd month so I'm a believer in the stuff. May have to go back on it for my GD but have to speak to my OB.

Hope you don't get many side effects. My only one was diarrhea.

Good luck Hun xx
