So me and my now ex boyfriend had been dating for a while and I am still a Virgin. So precum got on his hands before he fingered me which was 2 days before my fertile window and my period was late by 4-6 days but then it came on June 22-27. I’m usually a heavy bleeder but the day I had my “period” it was very light. Not in color but in flow. It was a light red and I saw clots in the first few wipes. However I usually have my period for 6 days heavy flow. It seems like I only had a flow when I stood up and the blood was scattered in small spots. Could it be implantation bleeding?
