Trying To Induce Labour - 40 Weeks Pregnant

Trying to induce labour at home as I am now 40 weeks pregnant and seriously fed up. So far I have tried: Pineapple, dates, sex, walking, lunges, birthing ball exercises, spicy food, clary sage oil, being positive, hot baths, membrane sweeps...I am beginning to think that baby just doesn't want to come out. Feel free to offer any additional suggestions to induce labour naturally.
