Not seeing doctor?

So I am currently 35 weeks and I had a appointment with my doctor maybe a weeks ago and he told me we are delivering when I turn 39 weeks which is December 13th and my next appointment with him is December 10th.. he still hasn’t gone over anything with me like he hasn’t given me a exact date for the c-section and I’m not being seen weekly.. I am however seeing a high risk doctor every two weeks due to having pcos and just having a c-section 10 months ago.. but I think it’s so strange I don’t have a set date for my c-section and my doctor isn’t seeing me until literally 3 days before I’m due.. he sees me every 4-6 weeks.. do you see your doctor weekly and do you have a date set yet if you are going that route?
