Are you concerned about going past your due date, and possibly needing an induction? The goal of labor preparation is to have a healthy birth, and go into labor at the correct time. Acupuncture can help promote cervical effacement and dilation as one approaches their due date.
Facing an induction, many people seek out acupuncture at the last minute. I council my patients to start coming in at week 37 for one to two treatments per week up to their due date, and beyond if need be. This allows us more time to prepare the body for labor rather then trying to coerce it at 41 weeks.
