Classical C-section

Anyone else have a classical cut on there uterus? I do because my second baby was born at 23 weeks 6 days and it was the fastest way to get her out well this will be my 3rd c section and just 2 weeks ago my Dr told me I could go to 39 weeks but today he said 36-37 weeks I was really hoping to go to 39 since I haven't had any complications this pregnancy f course I am going to do what is safest for my baby but I was just wondering how far did your Dr let you go before your scheduled section
