I tried many things, like evening primrose oil and red raspberry leaf tea, bouncing on a ball, walking, house work, nothing was working. I eventually tried the castor oil and was in labor the next day 

Nothing will work if your body isn't ready. I tried all sorts of things with my son and he was a week overdue. 

I tried everything sex, walking, squats, acupuncture, spicy food, basaltic vinegar but didn't try castor oil and nothing worked.
