16 and pregnant?

so i had sex with my boyfriend (we were each others firsts❤️) and i made him wear a condom but let him take it off half way through bc it didn’t feel good and he pulled out (extra early bc i DO NOT want any kids) and finished by himself, which i have zero problem with, but it took him like 45 seconds to a minute finish which means he was really close. is there ANY possibility that i could be pregnant? my period isn’t supposed to come for another 9ish days but i’m still a little paranoid. i know it was dumb, i just know my parents would kill me if i was pregnant.
