i need help ladies

ok so me & my boyfriend had been talking about having sex & the day after i got off my period i went over to his house. we didn’t have sex per say but he did stick just the tip in to see what it felt like. now i’m not on the pill & he wasnt wearing a condom, since then my period has been 8 days late but ive never really been one to track my periods. i know there’s precum & i know that it’s mostly dead sperm but could i be pregnant?
