My period is 3 YEARS late due to my PCOS and I started taking metformin again a week and a half-ish ago the day after I had unprotected intercourse. I’ve been spotting brown VERY lightly for the last 3 days, but IF I have my period it is VERY HEAVY. My cramps have been very mild compared to the past and my spotting has also had a few very small clots. Is this implantation bleeding similar like with my first 2 babies or is it my period?! I’m SOO confused and don’t want to test too early and don’t think my emotions can handle either +/- results! HELP!
