Could i get pregnant

I had unprotected sex on saturday, 2 days after my period ended. I've done a little research and it says sperm can live in you for 7 days to the most. (I'm not on any birth control and he cummed all 4 times) my fertile window starts tomorrow, but it said today and yesterday was 7% chance to get pregnant. So is it possible for me to actually get pregnant just 2 days after my period ended???
