Doc doesnt want to induce

I have 17 days left stomach is measuring at 43cm doc is concerned so next appointment I'm getting an ultrasound to check on baby however since I was 5months pregnant I've been in pain its hard to walk,stand,sit,turn (if I'm in bed) literally every movement I make feels like I'm breaking something! I've asked doc multiple times if I can be induced she is refusing at this point I don't know if I can go another 3weeks carrying this baby
