Can I get pregnant from that?

So yesterday we did anal but when he came he was either between my cheeks or some of the cum dripped out he’s done it this was before and I had the same paranoia till I got my period but I’m afraid it dripped down and when I tried to wipe I made things worse I’m not sure what to do since this isn’t a good time for us to start a family..honestly I feel so stupid and like a whore for being intimate with him since it’s not a good time for a child
