Why worry?

Statistically, babies born beyond 42 weeks gestation (but remember, it isn´t always easy to determine when you conceived, so determining 42 weeks can be difficult as well) have a greater risk of problems, often due to a placenta that ceases to function properly. However, this happens in only about 10% of the post-42-week babies. Deliveries can also be more difficult in post-term babies due to their increased size. Ultrasound examination can help determine if either of these conditions is present and may be preferable to induction, especially if there is any question as to the accuracy of the due date.
