help!

i put this in another topic but didn’t quite get the answer i wanted. but i guess a little bit of TMI

is it possible to get pregnant if cum that was inside the anus drips down on the vagina?

october 30th me and my bf had anal sex in the doggy position without a condom after he came he pulled out his dick, i then put my hand underneath my anus so just in case the cum would drip down it would go into my hand and not my vagina. there was a lot of cum on my hand so i’m 100% sure no cum went inside my vagina.

when i stood up i used my sock to wipe the cum off my anus and i flipped the sock and used the opposite side with no cum on it i used that side to wipe my vagina because it was really wet obviously cause we just finished having sex. and when i got home like 15 minutes later i got in the shower washed myself good (i know your not supposed to do this but i was scared and wanted to make sure) but i washed inside my vagina with water and a bit of soap.

i’m 100% sure nothing went inside my vagina but i’m still scared, i’m not having any pregnancy symptoms or anything like that but i’m still scared i’m only 15 and i am not trying to get or be pregnant. my period is supposed to come in 5 days. i wasnt ovulating when we had sex and i didnt ovulate before we had sex. but someone please give me reassurance and answers

thank you!!
