Soo my "period" started two days early and it started spotty (which is irregular) and lasted for 2-3 days it wasn't a heavy flow it was rather light and the last day the blood was brown. I did have sexual intercourse unprotected two days before ovulation. I have been peeing a lot and I have been having trouble sleeping. There IS a chance I could be pregnant I'm not assuming (if I was pregnant I'd be 4 weeks 3 days) I sort of do feel bloated and I have stabbing pains off and on.

How did you know you were ovulating?

You could be pregnant. I would wait for about two weeks after the start of your "period" and try a home pregnancy test. That is when they're most accurate. Implantation bleeding hasn't really been confirmed as a sign of pregnancy and many women don't see it. It has been seen to happen in a small segment of the population and everyone wants to be part of that special part of the population. Most aren't. It could have been a weird period or could be pregnancy. Can't say without a test.
