Pregnant or period

Hello wonderful empowering women and young women. My SO and I had unprotected sex on last Friday and he came in me so I know there is a chance of pregnancy especially since my period has not came yet. My period is not late and I haven’t really gotten anymore pms since he came in me. My period is supposed to come on within the next two days but semen can live in someone’s body for 5 days. My question is do you think that I could possibly become pregnant even if my period does show up?
