Can there still be active sperm which can cause pregnancy?

On my expected fertile window/ovulation week according to the app, my boyfriend ejaculated on my chest.. I wiped it with a tissue, fixed my bra and shirt, then I proceeded to the bathroom. I rinsed the tissue then threw it in the garbage then I rinsed my hand (can't remember well if I used soap but I know somewhere in between I did wash my hand thoroughly even my fingernails with soap and water) then I removed my shirt and bra to wash my chest then dried my hands on a towel before urinating and washing myself.

Now, my question is, could there still be possible active sperms on my hand when I washed my private part after all the things I did above? And if there was, could it still swim through water into my vagina to make pregnancy possible?

This may be a dumb question but we lack sex education here 😅
