really really scared

ok so me nd my boyfriend were at a football game last night & things got a lil heated between us so we went on a walk nd he told me he cheated on me so i kinda slapped him nd then he grabbed my neck nd started choking me (but in the sex/sexy way) nd pilled my pants down nd are me out, then we had sex nd then he hit it from the back. well on our way back to the game he told me he think he may have nutted in me nd know i’m scared because it’s too early to tell if you’re pregnant but i have this feeling that i’m gonna be nd my mom will absolutely kill me if i am pregnant nd i don’t know what to do 😭
