Unprotected sex!! Help😰

Me and my bf just had sex and he finished but for some reason...this is the second time but my vagina "eats" the condom. I freak out bc I was I didn't know where the condom was, I couldn't take it out of me, everytime I took out my finger from my vagina semen was on there. I wanted to cry. But I finally took out and tried to clean out my vagina as much as I could. My bf went to go get plan b and I took it right away. I'm super scared and hope I'm not pregnant. What are the chances of me getting pregnant 😰😰
