Using pump to bring on contractions?

Karisa
Hi, 
I've read where you can use your breast pump to stimulate your nipples to bring on contractions. Has anyone tried this? 
I'm a first time mom and only going to be 36 weeks this week so I won't be doing it myself (yet) but I have been very infatuated with ways to induce labor for when I get close or overdue. 
The only thing I have been doing is drinking raspberry tea, taking evening primrose oil pills, and bouncing on my excersice ball.
