weird discharge ⁉️⁉️

hello i just recently had sex with my bf and i'm just kinda confused/worried. i was on top of him doing our thing then he came and we stopped, i notice that afterwards there was white/creamy discharge i'm guessing all like over him. i'm really hoping that it was from me bc the condom didn't break but i am kinda concerned bc i'm 16 and still kinda new to this stuff. just trying to understand and hoping and praying i wasn't from him but please send more info if really appreciate it!!
