Weird question.. please read description

Weird question… Please don’t judge…

So I had sex with my ex-boyfriend all week during my fertile week, but I also had sex with another guy once during that week too..but I took Plan B the morning after we did it!

My ex and I are still trying to work things out but I am f*cked around with the other guy because I’m stupid lol.

Anyways. If I end up pregnant, it would my exe’s baby right? 

Plan B confuses me but I did take it the morning after me and the other guy did it so hopefully I’m in the clear. 😞
