Hi. I'm really quite nervous right now. I had my period early (1 week before schedule) with light to medium bleeding and lots of blood clots, and it stopped after three days. Not experiencing any cramps, or breast tenderness, etc. I had protected sex exactly 8 days before the "early period" started and my boyfriend and I are both sure that no ejaculation happened inside of me. No pre-cum, too. What could this mean?
