So I am going for my genetic testing ultrasound tomorrow and my sister has invited herself and my niece to the appointment.

Will they even let her in? I dont want her to even come but dont want to be rude.

My fiance and I have not been able to enjoy this pregnancy alone because she is always around and HAS to be included in every single thing.

Is there a chance it's just too many people to come? How can I let her down softly and tell her I would like for her to not come to anymore appointments?
