Is it wrong Im not going to want anyone in the room during birth

The dad isnt involved. And when im in pain i dont want others around. Im not super close knit with my family and i rather just be alone and suffer and have the baby alone and then let everyone around afterwards. Is that so bad?

Like what do i tell my mom or grandma? I know they were there during my sisters but i know myself and i know im not going to want anyone there. What to do??
