Birth control and sperm question

Hey guys,

So I have a question about sperm and birth control.

If I let my boyfriend cum inside of me twice in one night and I’m on birth control, should there be a worry for concern? I also let him cum inside of me 1-2 days before I started my next pack and I was on the placebo week.

I take the pills everyday on time and I haven’t missed a single pill yet.

I know I probably have no risk for pregnancy and it’s below 0.00001% but I just want that reassurance and personal opinion.
