Delivery room

So I’ve been reading over posts about who you chose to have in the delivery room, and I was just curious as to the specific timeline of who is present. Has anyone had maybe their mother or MIL in the room then kicked them out before it was time to push?

I don’t want to hurt feelings, but if it comes down to it I will for my own privacy. The thought of having other people in the room with my vagina exposed stresses me out. I know my mom wants to be in the room, but I know she will try to push boundaries and literally watch my delivery. I’m not sure about my MIL but I know she wants to be there.

Im 20 weeks and just trying to plan, this is also my first! Advice?
