Prepping my body!

I will be 37 weeks this weekend and the doctor is talking about inducing me at 39 weeks. I want to go into labor without being induced medically. I am trying to figure out ways to prepare my body over the next couple of weeks to hopefully go into labor naturally. Are there any specific ways to prepare my body? I don't want to go into labor now but I also don't want to go past my due date either.
