If your on metformin and if your overweight and on a diet, your symptoms will improve with
weight loss. Im on metformin 500mg 1x a day plus birth control. I also take a multi viatmin and another vitamin called Super B Complex (it has a ton of vitamin in it, also it helps with hair skin and nails, well thats what it says on the bottle) I've noticed while taking everything, my symptoms are getting better. My periods use to be about 4-5 days while on bc pills, now it last 3 days.
