Anyone?

So I'm just over 38 weeks pregnant now, and I've been given the green light from my doctor and midwife to start trying natural ways to induce labour! 
So far I've tried using my exercise ball to help get my little lady lower into my pelvis (though on my last appointment I was told she was Rather low already), I've walked a bit, I've had baths in lavender scented bubble bath, I tried a tiny bit of nipple stimulation last night which did give me some Braxton Hicks, but nothing more. And today me and the OH tried sex *blush* but that wasn't too long ago so I guess now I'll wait and see?
Does anyone have any suggestions? What worked for you? And also, if sex worked for you... How long did you wait until things started moving?
