Elective csect should be in which week? Share with me your experience.

Hi I am in week 36. Have not let the doc know that I want an elective csect for my delivery as on previous check up last week doc told me still early to decide on anything. My next apptmt will be next week and will be my week 37. Can you share with me when did you tell your gynae or doc about it and which week you went for your elective csect? Like a week before due date is it? Please share with me your experience. Many plenty thanks. #firstbaby #1stimemom #pregnancy #advicepls
