My Dr put me on 500 metformin once a day in September (last month) I added chromium and maca so now yesterday I noticed blood with jelly like mucus more like mucus show (not preg tested and and done ultrasound today things looked normal ) when I was wipping at the bathroom, then became darker blood as the day went by but Small amount, I thought anty flow was starting but it stopped no anty flow, today I feel a pain on the right ovary and have a dark brown discharge, would he spot pregnancy if it was implantation bleeding? He said it's might be infection and prescribed antibiotics hesitant to use them
