A sex a day after ovulation day

Hi! So Glow predicted my ovulation day for Saturday June 7, but I didn't get back from a girls trip until Sunday so fiancé and I had sex that night. According to the app I was still fertile but I've read that it's a low chance. Anyone gotten pregnant the day after the app predicted ovulation?

I'm new to this so haven't started tracking off the app (I know that's the best way to predict) but I am very aware of my body so I know I was ewcm around Wednesday & had high libido Thursday/Friday. I have an irregular cycle so it's possible I actually ovulated Sunday but not quite sure

I'm not actively ttc but not actively not trying to either which is why I'm not super informed of every little thing, but I have been pregnant before so also wondering if a previous pregnancy makes it more possible to get pregnant again ?
