Hey Doc, I Had Sex 3 Days Before My Period.

Hey doc, i had sex 3 days before my period. Im 6 days late and Im getting worried. We used a condom and he did not ejaculate at all. After a while I did oral On him and he ejaculated but I swallowed. There was no semen near my vagina. He washed off his penis when he ejaculated and peed. I dont know its stress delaying my period or if its pregnancy please help.
