What’s happening to your baby at 39 weeks gestation?
Congratulations, you’re almost there! At 39 weeks gestation, your baby’s lungs are fully developed, and they can breathe on their own if they need to. Your baby’s liver and kidneys are fully matured, and they’re ready to process waste and toxins efficiently. Your baby’s brain is still developing, and it will continue to do so until they’re well into their teenage years. But at this point in your pregnancy, your baby’s brain is fully capable of controlling their basic bodily functions like breathing, heart rate, and blood pressure.
Your baby’s head is now the same size as their abdomen, and their overall length is around 20 inches. Their weight is around 7 pounds, which is the average size for a full-term baby. At this point, your baby’s skin is becoming less transparent, and it’s taking on a pinkish hue.
Your baby is now in position for birth, with their head down and facing your back. When they’re ready to come out, they’ll descend through your pelvis and into the birth canal. The pressure from your contractions will help your baby rotate their head and navigate through the narrowest part of your pelvis. If you’re having a vaginal birth, your baby’s head will emerge first, followed by their shoulders and the rest of their body.
What can you expect at this stage of your pregnancy?
At 39 weeks gestation, you’re likely feeling very uncomfortable and ready to meet your baby. You may be experiencing more Braxton Hicks contractions, which are practice contractions that your body is using to prepare for labor. You may also be feeling more pressure in your pelvis, as your baby’s head is engaging in preparation for birth.
You may also be experiencing some other common late-pregnancy symptoms, such as trouble sleeping, heartburn, and a frequent need to urinate. Try to get as much rest as you can, and use pillows to support your belly and hips to make sleeping more comfortable.
At your prenatal appointments, your healthcare provider will be monitoring your baby’s position and readiness for birth. They may perform an ultrasound to check your baby’s size and position, and they may perform a vaginal exam to check your cervix for signs of dilation and effacement. If you’re experiencing any concerning symptoms, such as bleeding, severe pain, or decreased fetal movement, contact your healthcare provider right away.
What can you do to prepare for labor and delivery?
As you approach your due date, it’s important to have a plan in place for labor and delivery. Talk to your healthcare provider about your preferences for pain management, monitoring, and intervention during labor. Consider taking a childbirth education class to learn more about the stages of labor and coping techniques.
Pack a bag for the hospital or birth center, with items like comfortable clothes, toiletries, and entertainment for you and your partner. Make sure you have a plan for childcare for any older children while you’re in labor and delivery.
Most importantly, try to stay calm and trust your body’s ability to give birth. It’s normal to feel nervous or scared, but know that millions of women have given birth before you, and you can do it too!
