Ways to start off labour, HELP?

Walk...get up and move. Gravity helps the baby ease into position to give birth. Use a birthing ball.. walk up and down stairs, and yes have sex! Also, there are pressure points in your feet if you get it massaged its supposed to induce labor. My friend did that and LITERALLY that night went into labor, and her labor was only an hour. Maybe the baby was ready to come on its own, who knows but its worth a shot. You could try accupuncture or red raspberry leaf tea. Also there is castor oil and nipple stimulation. Of course talk to your doctor and get the green light first before trying any natural herbs or supplements! Will your doctor strip your membranes?
