Third Trimester 42 weeks pregnant

Pregnancy Week 42 - Post-Term & Induction Considerations

At 42 weeks, you are considered post-term. This is rare — only about 5% of pregnancies reach this point. Induction is typically recommended as the placenta may become less effective and risks increase. Your healthcare team will closely monitor you and your baby and discuss the best course of action.

Baby Development This Week

At 42 weeks, your baby is fully developed and likely quite large. Some post-term babies have long fingernails, dry peeling skin, and abundant hair. Your baby may have passed meconium (first stool) in the amniotic fluid, which can be a concern. The placenta may be becoming less efficient at providing nutrients and oxygen. Your baby is still active, and kick counts remain important. Most 42-week babies are healthy, but close monitoring is essential.

Changes in Your Body

Being 42 weeks pregnant is uncommon and can be very stressful. Your provider will likely recommend induction if they have not already. You will have frequent monitoring including non-stress tests, biophysical profiles, and possibly cervical checks. Your provider will discuss the risks and benefits of continued waiting versus induction. You might be feeling very frustrated, uncomfortable, and eager to meet your baby. Remember that the end is near, one way or another.
