MY father in the delivery room

So my half sister decided she wanted her husband, my mom, her biological mom, and our dad in the delivery room when she was giving birth. She had to have an emergency c-section though and didn't get to. &now that I'm pregnant, my mother thinks I'm going to ask our father to be in the room with me while I deliver. I understand it's my decision but I feel like I have to. I love my dad but I just don't feel comfortable with him being in there. What is yalls opinion on it?
