Has any one used a breast pump to induce labor? If so how did it go? What was the best way you found (ie pumping for 15mins each side for a hour or 5 min intervals etc)

38w today been 3cm 100% effaced and my cervix is all the way forward since Monday (the 11th) My body overproduces relaxin so I'm dying just walking. I've tried almost every other method to bring on labor. I'm trying to go naturally before I have to be induced next Thursday for medical reasons.
