Plan B failed??

My boyfriend and I are always very careful during sex. I am not on birth control (my body doesn’t tolerate it), so he pulls out 100% of the time and we’ve been successful with that for nearly 2 years.

This week, we got a little carried away and decided to have him finish inside me. We did this a total of three times over two days or so, and then I took the Plan B one step pill (I took it about 36 hours after the first time he finished in me).

This was yesterday that I took the pill. Today I checked my app to see when my period was due, and it turns out that I was ovulating the first time he finished in me (and likely still fertile the other two times).

I wasn’t too worried about it because I took the Plan B, but as I did some reading (I’m a nerd and a med student), I read that Plan B is considered ineffective if taken after ovulation, and I took it two days after I was due to ovulate. (Studies have shown that the other supposed way that Plan B works, by stopping the fertilized egg from implanting in the uterus, is not true... the only way the Plan B pill works is by preventing ovulation, but must be taken before ovulating for that to work).

Based on all this, does it seem likely that I will end up pregnant? Has this ever happened to anyone else and what was the outcome?

(Btw, my boyfriend and I are both in our mid-twenties, and we would accept however this plays out. I am still in school so I hope not to be pregnant at this time, but we will be responsible for whatever happens!)
