Hi all, posted here a while ago about hormone imbalance etc. I've been on metformin for a little over six months and last month my period showed up scarily heavy and shockingly finished within 5 days (usually last like 3 weeks). Today is day 14 of my cycle and got signs of ovulation. Is it possible that after 6 months in metformin my cycle regulates without any warning? I'm just a little shock and to be good to be true.
