Pregnant from pre cum?

Yesterday me and my boyfriend (both 17) tried to have sex for the first time. We started out with a condom but it just wasn't going on right so we took it off but we didn't get very far with the sex like the tip went in but it was very painful for me so we stopped but then I got worried I might get pregnant from pre cum so I asked him if there was any and he said "kinda" so now I'm really worried because there's only like 5 days until my predicted ovulation day could I be pregnant????
