I was a about a week and a half late on my period. But when I started it was extremely heavy which isn't normal for me. On top of that, it only lasted about 2 and a half days... And had a brown color to it. I've been having unprotected sex as well. Any idea what's going on?

You were late and it was heavy. It could have something to do with your unprotected sex but it could not. It could just be a wonky period, you're going to have a bunch of those in your life.

I will agree, women are late sometimes, sometimes light, sometimes heavy. Does not sound like pregnancy, just sounds like a late period.

Of course, pregnancy will happen, if you continue, unprotected sex
