Should I be worried ?

Okay so I am due January 20th and it is currently the 15th , but my body isn’t seeming like it’s trying to go into labor. My last doctor appointment I still wasn’t dilated. This is my first baby, but I don’t want to go over my due date because I know they will try to push inducing on me. I absolutely DO NOT want to be induced. So I guess my question here is how do I get my body to start inducing itself in a safe , healthy way. I’ve been drinking raspberry left tea , exercise, nothing seems to work.
