Need reassurance (pls be nice)

My bf fingered me yesterday after I gave him a bj. I basically cleaned up all the cum with my mouth but he still used a napkin to get a few little swimmers on his tip.. we made out and then asked to finger me so I said yes. I asked him if he has any sperm on his fingers and he said no because I had cleaned it all up for him.

Is there a chance of pregnancy here?

I keep telling myself there isn’t but I have an anxiety disorder and I am my own worst enemy rn so I just need some reassurance or the truth from someone because my period won’t be here until the 25th. Thank you.
