what are the chances of me being pregnant ?

i had sex 3 days ago with a condom and i am not on birth control. he started to put it on backwards on accident but flipped it around and put it on the right way. (this happens with every guy, somehow they still don’t know how condoms work🥴) this worries me every time but i’ve always been fine and have taken multiple tests and have gotten my period after. i am only worried this time because he had a lot of precum during foreplay and he also came on my back... also during sex i’m pretty sure he hit my cervix because at some points it hurt and i had to tell him to stop. anyway the next day i had pains very similar to period cramps and i’m worried. i’m not supposed to get my period for another 10 days so i don’t know if i should test now or wait. what are the chances of me being pregnant from this ?
