Am I fine?

I already posted about this but I want to just double check that I'm fine and don't need to worry. So I've been on nexplanon for 3 months and 4 weeks on July 13th I think a guy brushed his dick against my vagina I don't know if there was cum on his dick or not but if there was would I be completely fine and not need to worry. Please this answer and don't be rude since I already asked..
