What are the chances?

So I want to start by stating that my period has been pretty much on point the past half a year. I am not on bc (personal reasons) & I have been seeing the same person for about the same amount of time. Anyways my period was from 9/23ish to like 9/27ish…I’m guestamating because I just started using this app & not exactly sure but know it was that week. I had unprotected sex on Wednesday 10/9 and he def didn’t pull out and honestly I wasn’t expecting it because he usually does. I took plan b Saturday 10/12(I know I’m cutting it super close) anyways we also had sex Sunday 10/13 unprotected (again honestly seemed like he came inside me on purpose by the way he did it but I’ll save that for another post lol) I’m really unsure of when my ovulation date actually is but I just was wondering how high my chances are of getting pregnant?
