Scheduled C-section

I was diagnosed with complete placenta previa at 13 weeks. They said there's a small chance it could still move but not likely. They told me that I'll most likely have a c section to deliver. This is my second pregnancy and I've already been through the labor process but a c section will be very new to me. I was hoping to hear from someone who has had a scheduled c section and had any advice for someone who is going to have their first one? I'm very nervous but I know that its what has to happen to ensure mine and the babys safety and health. I would love to hear any advice to help further prepare myself. Thanks!
