Can I get pregnant from possible cum underneath fingernails

I have acrylic nails and I was giving my boyfriend a handjob, on May 19 .( he didn’t ejaculate) Then, on June 1st I masturbated ( fingered my self) is it possible that I could get pregnant if possible pre cum got underneath my acrylic nails from that handjob that happened a week ago without me realizing

or does it not survive that long outside

what are the chances of pregnancy?
