arguing over who can be in delivery room

I’m pregnant w my first and due in 10 weeks. I know I still have plenty of time to decide but family is making this stressful. I’m not for sure but I’m assuming that I can only have one person in the delivery room bc of covid, however I would like to choose a backup person just in case. My mom is acting like she has to be there and refuses to allow me to choose somebody else. She throws a fit whenever I mention the baby’s father being there. I’m not 100% sure if I want the baby’s father to be there though due to him denying the baby earlier in my pregnancy and treating me poorly throughout the pregnancy, plus he tried bringing his new girlfriend into an ultrasound and I don’t want to deal w him bringing her to the hospital while I’m giving birth. At the same time I thinking his child’s birth is something he should be there for if he’s going to get his shit together. My aunt is mad at me and threw it in my face that I must not love her since I won’t allow her to be there, but I’m not close w her and she didn’t talk to me for 2 years until I got pregnant. Today a women I go to church w got mad at me bc she found out she wasn’t an option to be there either, but she’s not even related to me or the baby and I feel like she’s the type of person to make it all about her. The baby’s fathers step mom asked to be there too but I’m also not close to her and didn’t really start talking to her until I got pregnant despite being in a relationship w her step son for a year. I’m just not comfortable w her. I feel like I have to choose my mom or she’ll be mad, and I haven’t even asked the person I have in mind as a backup yet. I’m thinking about telling everybody to get screwed and just doing it on my own. Would rather be alone w the help of nurses and doctors than listen to everybody fight and argue about who can be there, especially when half the people who want to be there aren’t close to me or even related to me or the baby. I just don’t know how to go about choosing who can be there w/out making somebody mad or sacrificing my feelings and who I actually want to be there.
