i’m scared i could be pregnant

[lolaappn]

hi guys, i’m coming on here because i’m scared i could possibly be pregnant.
i was on day 4 of my cycle and i had unprotected genital to genital contact with this guy. he did not penetrate or ejaculate but i’m scared there was possible precum. his penis tip was like on my vaginal area for like 5-7 seconds and i’m so worried.
after that, i got a bleed around two or three weeks later but im scared it wasn’t actually my period.
