Try evening primrose oil!! & sex, they both contain prostaglandins that should help you efface and dilate.
Dont worry that has happened to me with my first son. My doctor made me wait 10 until i was induced. I tried everything to go in labor an nothing happened sometimes different things work sometimes. My second was born four days earlier of his due because i wasnt dilating. Im 33 weeks with my first daughter hopefully by now i actually go in labor without being induced
I heard the raspberry tea helps speed up labor
