It is very unsafe to break your own water. I would just wait. Your almost there.
Pedicures can put you into labor. There is a nerve in your foot that cab trigger it that's what a friend of mine did.
Bounce on a ball or go on a bumpy car ride, walk, sex, cinnamon stick boiled in one cup water tastes bad but heard it works tho as long as labor has already started... goodluck
