So I some semen might have gotten in me, not for sure, this was on august 6th, then a couple hours later I got my period, I was expecting it. 2-3 weeks later I started peeing a lot, then about a week ago I spotted I think then a couple days later I got a period for 5 days, it was a couple days early. Seemed like a normal period dark red blood, a little more watery than usual though. I just finished yesterday, and yesterday I had heacaches and naseau throughout the day, today I am having it as well, as well as a lot of peeing.Could it be that I'm pregnant?
