Need advice. Teen mom

Hannah
Hi guys. I had gotten pregnant at 17 years old, but I turned 18 three months after. Anyways, I'm 40 weeks and 2 days and I'm getting induced in 5 days, and my sisters, (ages 16,21,23) think I don't have a choice if they're in the room or not. I don't care if they're in the room just chilling with me, but for the pushing I'm only having my mom and boyfriend. But they're saying they don't care, and to try to get them kicked out and making it about them. I don't feel comfortable with them in there and I feel as if I have the right to do whatever makes me feel more comfortable. But then again I don't want to hurt their feelings. I'm not letting them in the room period, but i just don't need the stress of my three sisters in there.. It's not about them, it's about me and the baby's father and the baby. Any advice or things I should tell them? They're getting really annoying and with me, I have a huge heart and don't want to hurt anyone, but I need to do what's best for me and our experience. Thank you guys
