castor oil?

Miriam
So I've been 1cm dilated for the last 2 weeks. Had a membrane sweep done today which prob won't work bc I'm not dilated enough. Dr went in as much as he could. I've been eating pineapple, bouncing on ball, sex... Nothing is making baby boy come out. I'll be 39 weeks tomorrow. Now I'm tempted to try castor oil... Should I?
