If you are overweight, and of course
taking metformin you should start losing weight along with diet. Therefore,
you could start having cycles and normal cycles for that matter, as well as also ovulating on a monthly basis.
I take metformin twice a day 500mg, but I am also on birth control. Before knowing I had pcos, I always had a cycle every month...just was very irregular and heavy. I gave myself a 6 month break from the pill, and only stayed on metformin...
