Study End Date
In this study we are looking at the effects of induction of labor and outcomes for moms and babies at 39 weeks of pregnancy in comparison to moms who go into spontaneous labor or who have labor induced at a later time in pregnancy. Prior medical research has shown that being induced at 39 weeks improves your baby's outcome. While everyone agrees that unless medically indicated, women should not be delivered prior to 39 weeks, the exact best date for delivery of your infant is unclear. In this randomized trial, half of the women who participate will be randomized to induction at 39 weeks and the other half of the women will be randomized to expectant management (unless medically indicated).
