I skipped my induction appointment with DD1. It was booked for 40+4. She came naturally at 41+1.
I didn't know back then that I could argue with the ob & called my gp for advice. He said he won't even talk about an induction til 7 - 10 days past due.

Try a long walk? It might wear you out a bit, but its the one thing that got my babies moving.
