unexpected guest?

T
How do y'all feel about unexpected guest? My fiancé and I recently moved into a new place I have a big family and his mom always say someone gone be here everyday(which isn't true) my parents and brother was over here (but my mom called to make sure it was ok to come) and then there's a knock on the door... his mom popped up. I don't mind her coming but I hate pop ups! And that's gone add fuel to her fire that my family is gonna be here all the time smh I'm 8 months pregnant and extremely moody and mad as hell!..he doesn't see a issue with his mom popping up but I do because this is just not his place and my mom doesn't just pop up she calls first.
