Could be you have not gone into labor yet because your baby is not in the correct position to kick off labor. If you agree to an induction, labor will begin with a malpositioned baby. This increases your risks for long labor, birth trauma, and c-section. If all other tests are coming out fine, I would not agree to an induction. Babies squish when they are bigger. Better to have a correctly positioned bigger baby than a smaller baby that is coming out crooked or face up.
Exercises that can help your baby into the correct position are: pelvic tilts, bouncing on an exercise ball, sitting on the floor with your legs crossed (Indian-style). Also, you can visit the website www.spinningbabies.com for other helpful ways to help your baby be positioned correctly.
