i can’t stop crying.

i’m 13. please don’t hate i’m already freaking out but i had a guy over 2 nights ago and we almost had sex but i stopped him. but the tip was outside my vagina but there was barely any penetration and i’m supposed to get my period in 4 days and i stopped ovulating about a week or so ago. do you think i could still be pregnant? could really use some reassurance!
