Kinda scared

I got a question , so my boyfriend and I had sex on the 10th and It was my fertile day and I think he came inside me but he wasn’t sure so just to be careful we got a plan b the next day but before we got the pill we had sex one more time but this time he actually did come inside me so after that we went get a plan b and I took it but then again we had sex again today and he says he didn’t come inside me but i don’t know and I just want to take another one just to be sure but the point of all this is I need to know if I’m going to get pregnant even though if I took the plan b already and btw tomorrow is my ovulation day so I’m kinda freaking out
