Is it normal to be scared of...?

So About 2 weeks ago i was raped by my uncle. i dont remember most of it and the only reason i know i was is because when it happened i was on my period and when i went to pee the next morning i wasnt in any underwear and the tampon i had had the previous night was shoved to the very wall of my vagina to the point where it was almost stuck there.... i dont remember anything but him being over me and i think he might have tried to fuck me. im now on my period again and i havent been irregular like this in a very long time... could i be pregnant?

im terrified and i dont wanna be scared for nothing..

i cant tell my mom because i was drinking and it happened afer i passed out and plus it would fuck my whole family up... some advice would be greatly appreciated
