Im so confused — is it possible that I conceived last night ?

Okay so my bf and I just recently started using condoms because I stopped my BC. But last night at the end the condom came off inside of me and once I got a hold of it and pulled it out there was barely anything in it. I checked my phone because I have multiple trackers but for some reason they’re suddenly not in sync. The first day of my last period was Sep 19 (I have a 28 day cycle) but I had multiple online calculators say that I would hit peak ovulation last night (Oct 3- cycle day 15) but very few are saying I probably ovulated days ago. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">EVE</a> Is saying my fertility window ends today (Oct 4) Nonetheless I know there’d be no point in getting plan B because it’s allegedly already past my ovulation… but idk. How worried should I be??
