Please help!, Emergency!?

Okay. Today, My boyfriend came over to my house and we did oral on each other. [ONLY ORAL] He came on my face. The *** later [like 2-5 minutes] dried on my face. His penis did not touch below my waste AT ALL {just between my butt cheeks but didnt touch my crotch but this was before he came. after he came, he didnt put his penis between my butt cheeks anymore} then later [like 5 minutes later] he came again on my belly. He took some of the ***, and put it in my mouth,( i swallowed it but i could still tasted some on my tongue.) Then we made out for like 10 seconds and then i say "eat me". and he goes down to eat me out but he like doesn't lick my opening he was licking the top of my clit for like 5 SECONDS and he was like "wait. bad idea" (we've had some pregnancy scares in the past so that's why we were being really careful). so he wiped my p**** off with his hand. AND we wiped it off with a towel. AND i peed {even though i ALREADY KNOW i don't pee out of my vagina}. AND i washed up down there with soap and everything. Just wondering, I'm probably not pregnant but i just need 100% assurance because I'm like an oover-thinker and i think A LOT. And just wondering if *** spreads because i wiped it off of my p**** and i washed up down there?? The school I'm at, we don't take sex ed till 12th grade so i know like NOTHING about this (yeah i know i'm stupid for even doing it in the first place)
