Has anyone told someone you are close to that you were pregnant not long after you found out?

I’ll be 4 weeks pregnant or just over at Christmas and will be at home with my parents. We probably wouldn’t have told them yet but I don’t want anything to give away that I’m pregnant although they wouldn’t have a clue we were trying. It also does feel strange knowing and not telling them. Did anyone tell close a family member/friend you were pregnant early?
