My bf ejaculated in me ... Period in 2 days

My period is expected to start in 2 days my bf and I were having sex and ejaculated in me. I was just wondering that if I was to get pregnant from that would this period still come on time, be late, not come at all , or would my NEXT period be missed? I don't need anyone explaining ovulation and fertile Windows and that stuff.
I get all that and I know it's practically impossible but I have heard of this happening and I want to know if anyone else has had this happen to him & ended up pregnant ...
