Having had 2 sections myself, and not gone into labour - I probably shouldn't comment, but I just wanted to say try not to be anxious about going overdue. Try all natural induction methods to help your body along, and just try to relax and let whatever be - be.

If you stress out too much, it can stop labour from naturally occuring - which is a double-edged sword cos all you want is to go into labour (believe me, I know - I was 2 weeks overdue with Miss M and had a c-section)

So thats my advice. Try not to think about. Take long showers and try to bond with your baby and release any stresses you think are holding it back.
Good luck with your VBAC.
