I had intercourse Sunday in the middle of ovulation and then a week later on Sunday again. I haven't had any signs of starting my period like I usually would, and wasn't swollen at all during intercourse, so you could imagine how surprised I was when I started my period the day after having sex on the second Sunday. I'm two weeks early. Did having sex just kick start my period by two weeks or is this something else?Could I be pregnant?

Both times were unprotected.
