Yoga ball to induce labor

** UPDATE**

The ball helped with effacement, but not much luck with dilation or contractions. It took 4 weeks to get to 1 3/4 dilated and my Dr has scheduled for me to be induced Monday at 41 weeks 3 days and has had me sent to l&d 2 days in a row for non stress tests and labs due to blood pressure being high

Anybody had any luck with using a yoga ball to help bring on labor? I'm 3 days over due and trying my hardest to bring labor on without medication or at least be dilated to a 3 by my next appointment and I've done everything except sex (so is currently 2 hours away) or any kind of medical type of thing. I'm getting kinda desperate
