How would you feel/react

If on more than one occasion people have asked you and then your fiancée (who you've been in a relationship with for 9 years) if this pregnancy was your first baby? Like they'll ask me and I'm thinking that they really are asking us both then they turn to him and ask "is this your first too?". I feel like it's really rude and disrespectful to ask that. It's happened on more than one occasion which is why I think it's bothering me more.
