Someone give me some kinda advice

Good afternoon … I am currently on the combination birth control pill . I take my pill every single day … well today I took my pill and I have talked myself out of it … I feel like somehow it came out,,, after I took my pill I felt kinda nauseous and I know I didn’t puke because there’s no puke anywhere ….. but I’ve talked myself into it

Anyways

I had sex Monday and he stuck it in a few times before putting the condom on … and then I had sex yesterday and he used a condom the whole time ..

If I missed the pill or made it inactive today would that make me fall pregnant?
