A month late!?

I was almost a month late for my period! The other day my boyfriend and I had sex and it was a lot rougher than usual and I bled for a little while after but then it completely stopped! Then yesterday I started bleeding again I'm not sure if it's my period or not because my period isn't suppose to come next week if I was to get it. Could this be an early period or an I still bleeding from the sex? It's been 4 days since I bled from sex.
