I’m so confused/anxious/frustrated.

I’ve been walking around for two weeks now at 3 to 4cm dilated fully effaced. I’m 40 +3 weeks and this is my third baby! I never even imagined I would go this late. My last baby was on her due date and my whole labour was 6 hours start to finish. I’ve been so on edge the last few weeks thinking I could go any moment and that it would likely be quick but now it’s looking more and more likely that I will be induced which I really want to avoid. I’ve had multiple times that I’ve had timeable contractions that I couldn’t walk through that just spontaneously stop after 6/8/10 hours. I’m so drained at this point. Has anyone else experienced anything similar with a second/third baby?
