My c/s wasn't booked in until a week or so before. I had placenta praevia and had an u/s at 37 weeks to determine if it had been resolved or not. So when I went to see my ob the following week with the results I was almost 38 weeks already, before I had the c/s booked in for the following week, at a day shy of 39 weeks.

It was a private hospital, I was booked in to go there from 20 weeks.
