Let know 😭

So I just had sex with my boyfriend and we didn’t use condoms I lost my v card because I bleed a lil because he hit it but not all the way because it hurt but I bleed for a day. I thought it last for like 2 days or something idk. So once I got home and use the bathroom I see white stuff come out of me idk if it is me or was it his cum. I’m scared I been lookin at my stomach all day. Hoping I’m not pregnant. I asked him did he cum inside of me and he told me no but idk if it was my discharge or what. I’m nervous and it was only my first time. What do y’all think I should do ? Please help.
