C section question

How early does a doctor allow you to schedule a csection? Both my kids came at 37 weeks and both had extreme complications. My last pregnancy was an emergency csection and I'm trying to avoid having those same complications. I want to do it at 37 weeks but dont think the doctor will that early.
