Could I be pregnant

Long story short the condom book on vday and he definitely came inside. I took the morning after pill 3 hrs later and it turns out I was on my last “fertile” day according to eve (my peak was 3-4 days prior) could I end up pregnant?? I’m so stressed out and just need some support.. currently have a stomachache and idk if it’s from the pill, anxiety, or a fetus forming ugh

(Btw we use FAM to not get pregnant so condoms on fertile days this just happened to slip my mind)
