There is a law that they can not induce or help labor along before 39 weeks. I was 37 week and dialated to 5 and having regular contractions and my dr. told he his hands were tied until I was 39 weeks. After 4 days which one of the nights were in the hospital I started to dialate more I had my baby. I was 37 +2.
It's always 39 weeks unless an issue
They don't schedule them until your 39th week usually due to insurance reasons unless there is a medical need to do it sooner such as high blood pressure or labor.
Unless there is a medical reason I don't believe they will schedule a csection or induction until 39 weeks
