Plan b & ovulation :(

Hello : (i havent hooked up or had sex in forever. I hooked up with a friend & we used a condom. It looked to not be broken. But i think towards the end when he nutted it kinda.. slipped off? Idk. I got paranoid because i couldnt tell if the wetness was my nut or his & we used a condom... so. The next morning i was able to get a plan b and took it. I took a plan be twice 2 years ago & was perfectly fine after not using a condom lol. Im just worried because the day we had sex it said i was MOST FERTILE ON MY FLO APP.. .... i also live in fl & i cannot get... yk... a bye bye baby procedure IF that was the case.... im praying so hard that im ok & get my period when i should get it like i did in the past. I also remember tana mongeau saying shes taken so many plan bs and has been fine. Im just paranoid. Anything to ease my paranoia would help : ( does plan b still work effectively if you take it during ovulation?
