Overthinking and stressing myself out

So I’m due January 22nd and they have scheduled my repeat csection for the 21st. I went into labor with my daughter at 39 weeks. (I didn’t know my water had broke or that I was in labor just a backache) I should add this will be my fourth csection. I was close to my doctor and the hospital so it wasn’t a big issue. But I’m seeing a new doctor and going to a completely different hospital 2 hours away now. During the winter we do get plenty of snow and ice. So I’m scared of going into labor and not being able to make it to my doctor in time. Like I consistently have a backache little man is occiput posterior. So I wouldn’t know if it was the same thing or not. Kinda worried of rupturing before I get to the hospital or giving birth in the car.

Has anyone had something like that happen?
