Baby Development

What's happening inside the womb this week

Week 39 focuses on final maturation. The lungs, brain, and nervous system keep developing while fat stores increase for temperature control after birth. Sleep-wake cycles and movement rhythms are usually more noticeable.

As space becomes tighter, movements may feel stronger but less acrobatic. Your baby is preparing for delivery, and regular monitoring plus symptom awareness becomes especially important.

Your Body This Week

Physical and emotional changes you may experience

In week 39, increased uterine size can lead to pelvic pressure, shortness of breath on exertion, sleep disruption, leg cramps, and frequent urination. Braxton Hicks contractions may occur intermittently.

Prioritize rest positions, hydration, and monitoring fetal movement. Seek urgent care for fluid leakage, bleeding, severe headache, reduced baby movement, or regular painful contractions before term.
