Unprotected sex during ovulation

So my boyfriend and I are ALWAYS careful during sex until today on vacation he didn’t care lol. My actual “ovulation day” is on Saturday ... this is the very first time he hasn’t pulled out ... I’m confused when it comes to ovulation with this app and the Green Day’s leading up to the “ovulation day”, I am on day 3... are my chances high ?? A plan b was considered, but I’m thinking it’s pointless if I’m already ovulating correct ?
