For those of you who are going in for sweeps or when you become overdue, the acupuncturist showed me a pressure point which is supposed to encourage ripening of the cervix.
If you feel for your ankle bone on the instep side, then it's about 3 fingers distance above that, up your leg.
It says contraindicated during pregnancy because of course you shouldn't be trying to ripen your cervix until baby is fully cooked!
