Is Pregnancy Possible If Intercourse Is During Menstruation?

Me and my boyfriend had unprotected sex while on my second day of my period, he ejaculated in me twice. I still bled a little while after that as if i was still on my period, but an hour or two later i quit bleeding and its been a day and i still haven't started bleeding again, my periods usually last 4 days. Should i be worried? Or could i be pregnant?
