Plan B During Ovulation

Me & My boyfriend had unprotected sex where he admitted to accidentally 🥜 in me. I checked my app and it said I was very fertile. This was Monday Night around 11 pm. My First Ovulation started on that Wednesday, but for some reason, I didn’t take the Plan B until Wednesday around 12 pm, so roughly 36 hours after unprotected sex. I am not supposed to get my period for another week, so there’s nothing I can do as of right now, but I wanted to ask what you guys thought. & if there was any chance I could potentially be pregnant.
