So I recently suffered an miscarriage and I have now been spotting for a little over a month straight with a small period in the middle. My periods have been very regular up until January of this year, then it seems it all went to hell after that. So my dr just put me on 500mg of Metformin twice a day. Has anyone ever used this and helped with pregnancy?
