Acupuncture to induce labor

Joshalynn • Mom of a beautiful boy Samson, 5 years old. Another beautiful one due Sept. 1st 2015!
I'm 39+2 and my midwife would really love for me to deliver this week. I'm trying for vbac and we all know how hospital want to intervene once you go past 40 weeks. She has suggested acupuncture since it helped her go into labor once. She says it won't start my labor if my body isn't ready. Anybody else ever tried any kind of acupuncture?
