Stories on Metformin

After almost 9 months of trying, i scheduled an appointment with a fertility doctor, for July (Soonest i can get in) so by then we'll have been trying 11 months but anyway i went through my PCP to get my thyroid tested and they spoke about putting me on Metformin for weight loss (been dieting an working out with no weight loss) and said that my fertility doctor also use metformin for TTC, so it could be a win-win.

Anyone have stories on this? For either losing weight or becoming pregnant?
