Can you get pregnant from anal

I’m 4 weeks pp and I had anal last night with my husband. Can u get oregnant ? I know that sounds stupid but I have people telling me I should have used a condom because the cum can get inside of you? He came in m butt lol 😑

EDIT - no shit I know you can’t get pregnant from just anal. I’m asking if it’s possible that if it went down into my vagina that I could get pregnant. God I love all these sweet caring women 🙄 thanks to the ones who are actually nice people
