So disappointed!

My OB was on vacation for a month, so I've been seeing the doctor covering for her, and I've repeatedly asked about scheduling my c-section. I always got the reply "you've got plenty of time to book it." Today I saw my regular OB for the first time in over a month, and when she went to book my c-section for November, we the news that there are no openings until the middle of December. My due date is November 30th, and I'm at high risk due to an abnormality with my uterus, Polyhydramnios, and gestational diabetes. We're worried about uterine rupture as well, which is why we are going with a planned c-section. I feel like crying because now I basically have to wait for labour to start/my water to break and deal with an emergency c-section. All because the other doctor didn't take me seriously.
