Pregnancy Week 39: Your Baby Is Ready to Arrive
Pregnancy week 39 is an exciting stage because your baby is now considered full term. At this point, most babies are fully developed and ready for life outside the womb. Labor may begin at any time during this stage.
Although your due date is close, every pregnancy is different. Some babies arrive earlier while others may take a little longer. The final days of pregnancy are often focused on your baby continuing to gain weight and your body preparing for labor and delivery.
Many women continue feeling regular baby movements during this time. Movements may feel slower or more like stretching and shifting because space inside the uterus is limited.
As the due date approaches, many parents feel a mixture of excitement, anticipation, and curiosity about when labor will begin.
Baby Development at Week 39
At thirty-nine weeks pregnant, your baby is about the size of a mini watermelon and continues gaining weight during these final days of pregnancy.
Your baby’s organs are fully developed and prepared for life outside the womb. The lungs, brain, digestive system, and other major organs are ready to begin functioning independently after birth.
Your baby’s brain will continue developing rapidly after birth as the baby begins interacting with the surrounding environment.
Your baby’s body continues building fat beneath the skin, which helps regulate body temperature and supports healthy growth.
Most babies are positioned head-down at this stage in preparation for delivery. This position helps the baby move through the birth canal during labor.
Your baby may still move regularly, although movements may feel slower due to limited space in the uterus.
Common Symptoms During Week 39
Common experiences during week 39 include:
Pelvic pressure
Frequent urination
Back discomfort
Fatigue
Braxton Hicks contractions
Pelvic pressure often increases as the baby settles deeper into the pelvis. This position helps prepare the body for labor.
Frequent urination may occur because the baby’s position places pressure on the bladder.
Braxton Hicks contractions may also continue during this stage as the uterus practices for labor.
These symptoms are generally normal signs that your body is preparing for delivery.
Changes in Your Body
Your uterus has reached one of its largest sizes during pregnancy.
As the baby moves lower into the pelvis, you may notice increased pressure in the lower abdomen.
Your center of gravity may shift as your baby bump becomes heavier. This shift may affect posture and sometimes contribute to back discomfort.
Your body continues producing increased blood circulation to supply oxygen and nutrients to your baby through the placenta.
These physical changes are part of the body’s preparation for labor and delivery.
Signs That Labor May Be Near
As your due date approaches, many women begin watching for signs that labor may begin soon.
Possible signs of labor may include regular contractions, lower back pressure, or the breaking of the amniotic sac.
True labor contractions usually become stronger, longer, and closer together over time.
If you notice regular contractions or other signs of labor, it is important to contact your healthcare provider for guidance.
