when did u start inducing natural labour

Hey all, I am 29 wks with twins. When did u all start natural remedies to go into labour? How many weeks were you? What natural remedies worked for u?
I've had strawberry leaf tea for my other pregnancies but my kids were still over due ( Iam thinking maybe I started drinking the tea too late. I started when I was 37weeks) and I really think the tea never worked for me.
I really don't want to be induced again with twins. I just wish they would come on ther own. Doctors said I have until I am 38wks.
Help a girl out am so worried about the pain waiting for me
