OCD and pregnancy chance?

Okay.. please no rude comments I know this might sound crazy. I have my first boyfriend and we just started to become sexually active but I’m freaking myself out over things and I want to be prepared. I have bad OCD. I went to his house and ended up giving him a handjob.. he didn’t finish In my hand. But I might have gotten Precum on my hands. I them drove myself home ( 10-15 minutes) and I went to the bathroom but forgot to wash my hands off first.. is there anyway if I can some pre cum on my hands it would’ve made it to the toilet paper and gotten me pregnant?
