What Are The Chances Of Pregnancy After Protected Sex?

hello , i a, luis 21 years old. I had sex with a girl and then i came inside her and still fucked her a bit of time until my penis got soft , then i wanted to take my penis out of her vagina then the condom lefts half inside her vagina and the other half is out her body. the question is, is there any problem her? was there any fluid exchange between me and her?
