What Causes Bleeding And Soreness In The Vagina After The First Intercourse?

I lost my virginity the night before last, or to be exact, about 32 hours ago. I'm on birth control pills and he's been tested since his previous partner and doesn't have any STD's, so we decided to do it without a condom for my first time so it would feel the most natural. When we did it, it hurt for about the first minute or two and it bleed a pretty good amount (I had a pretty thick/strong hymen). Now my vagina is only mildly sore to the touch, but it's itched a little since a couple hours after doing it. Like any other itch, it itches worse when touched, but when I leave it alone, it's not that noticeable. When I have a cut/scrape/blister/etc., it almost always itches when its healing, and I also start healing very quickly after having a cut/etc. So I'm thinking this is the case with my vagina healing from the hymen being torn. The bleeding has nearly stopped now and there is no abnormal discharge. So is the itching coming from my vagina healing where my hymen was broken, or is it more likely that it's something else?
p.s. This says to mention my age/height/weight. I'm 17/5'1"/125 lbs.
