Help!! Could I be pregnant?

I had a hot night with a guy two days ago and he came on my breasts but it was very liquid like and so it ran down until my panty line and I’m not sure if maybe some liquid maybe could have slipped through to my vagina and I’m super worried because I didn’t have any protection and I did shower but I worried it made the sperm run closer to my vagina... what should I do? Could I pregnant?
