Virgin, Just had sex for first time and im bleeding!! HELP

So Im a virgin, and today my boyfriend and I had sex for the first time today. As soon as it went in, it really really hurt! We did it again a second time and it didnt hurt as much. We used a condom and he still pulled out when he ejaculated. Then when we finished i went to the bathroom and saw i was bleeding. So now, its been HOURS and im still bleeding. Im freaking out!! Is this my period or is it just a tearing of the hymen? How long will the bleeding last for? Really scared, someone help please!
