Could I be pregnant? please answer?

I lost my virginity a couple of weeks ago, It was right about the time I was expecting my period. (so it should technically be a safe time? although we did use protection too ofc) During the i bled a little, and after quite heavily, which continued for like 4 days and I thought it was from breaking my hymen but I haven'tgotten my period soooo could this have been my period?! I'm kinda freaking out.
