Pregnant?..

So I had sex a couple weeks ago and the condom broke...not majorly but it broke. He didn't ejaculate inside of me but there's the pre cum. We stopped after he broke and I got my period 1 or 2 days later but it's just a scary thought and I would like to know wether you think I could be pregnant or not. I researched and it's highly unlikely but it's still scaring me.
