Broken hymen?

So, I'm 20 years old and lost my virginity on April first (April fools! But seriously). Yesterday I had sex with my boyfriend and all of a sudden it was really painful and yes I'm at the end of my period but I started really bleeding all of sudden. I can't remember ever breaking my hymen in the past, but he certainly hasn't been gentle down there and I can't figure out why only now, when he was being fairly gentle it would break? Is that normal?
