Having your mom in the delivery room

Hey everyone, I am just wondering what some other opinions are on this, I am 28 weeks and 3 days with my first baby, and i told my mom and my husband's mom that it was just going to be myself and my husband in the delivery room at the hospital. My mom keeps making me feel guilty because I don't want her in the room with me. She always says oh well if my mom had been alive when I delivered you she would have been in the room with me. I just feel like my delivery would be a lot less stressful if it is just my husband and I in the room. What are some of your opinions on this? She's starting to stress me out.
