Missed period. Help calm me down 😰

Katie

My boyfriend and I had sex 2 days after my week of ovulation. We barely even really had sex he probably only had it in for a few minutes with no protection and then we were done. There could have been some minor pre cum not much if any. I have looked up and saw you cannot get pregnant from pre cum alone it has to have traces of actual cum with it that get carried within the urethra. And we know know he hadn’t cum in a while. I’m now 6 days late and I’m just getting anxious. I know our chances are really low I just don’t know how to calm myself down. I had one other time where we didn’t do much and it was really late. Does anyone understand, or know how to explain this or give me any advice? Anything would be appreciated
