Closer to mom during pregnancy

My boyfriends mom is excited to become a grandmother, but I feel like she's pushing boundaries when it comes to being involved. For example, I want my mother in the delivery room, but she got upset when she found out she wasn't allowed in the room due to my privacy and shyness issues. Another thing is, she doesn't understand that a mother and daughter get closer when a daughter becomes a mother. This is why my mom is more involved. I'm my moms only daughter, she has two of her own, which she should wait until they become pregnant to be as involved. I can't even mention that my mom is coming to an ultrasound with me because she will get upset and cause a problem with my boyfriend. My mom and mother in law don't get along and quite frankly I'm not close enough with her for her to be around me much. Anyone else have problems with their mother in law while pregnant?
