Is there a chance of pregnancy?

So, last Friday my bf and I had sex and for the first time he came inside me. I had checked this app to see the chance of pregnancy and it said none, and I still had five days till the ovulation part of my cycle, so we thought why not. Well I checked my calendar on here yesterday and today and though it’s not high percentages, there is still a 7% chance (and that’s just gonna keep going up). I’ve also been told sperm can live up to five days inside you. So I’m a little concerned right now. Opinions please! I need help/advice!
