Could i be pregnant?

For starters, im 17 and just started school. My period is already like 2 days late from schedule change (sleep, school, etc.). My bf and i didnt use protection and pulled out, so i took a plan b just in case. We did it again(he pulled out) an hour after i took it. Will my period come soon and what do you think the chances are? (Please dont shame, im fully aware this was a horrible idea and we've sworn to never do it again.)
