38 weeks and still not dilating

Amanda
Has anyone else had were they weren't dilating still at 38 weeks but still has baby before 40??? 
My doctor leaves for vacation next week , and she wants to induce me before she leaves but I have to be dilating by my 39 week apt Friday. 
I'm so worried I won't be and will go over and my doctor won't be able to deliver her. 
Any words of hope or advice or things I can do to get myself dilating??
