Just a quick note...
Being 'long' just means that your cervix is still long, not effaced. It starts out long , thick and tough, then softens, starts to thin and spread out, becoming shorter. HTH
I was 38 weeks, 1 cm, and not effaced, at 39 I was 3 cm 50% effaced, and stretched easily to 5cm, so maybe things will moe well for you and no induction will hae to happen!!
