Mother trouble

Anyone have a mother that automatically assumes that she is welcome in the delivery room? Mine is trying to guilt me into letting her. I’m a very modest person and don’t want anyone other than my husband in there. She even tried to get me to either agree to FaceTimeing her in or to be on a phone call when I deliver. I mean wtf. Why can’t the birth of my first child be a private moment between my husband and I? So frustrated right now.
