Weekly highlights
- 1Baby’s Development. Your baby is now full term! Space is tight, so you may feel more rolling and stretching than sharp kicks. Call your provider right away if movement decreases. Lungs are producing surfactant, and both the lungs and brain will continue to mature after birth.
- 2Bodily Changes & Symptoms. You may experience trouble sleeping, difficulty moving, Braxton Hicks contractions, or passing the mucus plug. Water breaking may also signal that labor is near. Keep watch for signs of preeclampsia—such as swelling in the face or hands, headaches, sudden weight gain, or vision changes—and contact your provider if they occur.
- 3Health & Wellness. Early labor contractions are often irregular, 5–15 minutes apart, and last about 60–90 seconds. True labor contractions grow stronger and more regular. Call your provider for contractions that intensify, water breaking, heavy bleeding, or any concerning symptoms.
- 4Tips & To-Dos. This week is all about being ready. Keep your hospital bag packed, protect your mattress, and have newborn supplies on hand. Discuss induction, assisted delivery, and immediate postpartum practices with your provider.
Checklist for week 28
- Take a moment here and there to enjoy those little kicks and your final few days or weeks of being pregnant. You’ve come a long way, and you’ll soon meet your baby. But whether you’ve found pregnancy mostly exhausting or mostly magical—or a mixture of both—taking a moment to soak in the feeling of being pregnant is worth doing. It’s a period you’ll remember forever.
- If you’re still at work, start wrapping things up and leave notes or onboard your colleagues who’ll be managing things while you’re on leave.
- If you plan to bottle feed your baby, stock up on baby formula.
- If you like the idea of keeping details of your little one’s first year written down, buy a “my first year” baby book as a memento.
- Plan and confirm who will take care of your pets and older children when you go into labor and during your hospital stay.
- Get a baby first aid kit and have it stocked up.
- Protect your mattress with a waterproof sheet or cover in case your water breaks during the night.
- Finalize your choice for your baby’s pediatrician.
- Contact your insurance company to ask about the availability of a breast pump.
- Make sure you have the right diapers for your newborn.

39 Weeks Pregnant: Your Symptoms
At 39 weeks pregnant, you may be experiencing some of these symptoms:
How Big Is a Pregnant Belly at 39 Weeks?
Your uterus has expanded over the course of your pregnancy. It started out weighing about two ounces before you were pregnant, and it’s now grown to weigh about two and a half pounds.
After you give birth, your uterus will gradually shrink back to its pre-pregnancy size and settle back down below your pubic bone. After about six weeks, it should be back to its normal size.
It’s also common to be concerned about your baby’s movements during this period. Many parents wonder if decreased fetal movement at 39 weeks is a sign of labor or if a baby moving a lot, or a feeling of pressure, could also be a sign of labor. Every baby is unique, and only you truly know your little one’s movements; however, it may be common to feel fewer kicks at 39 weeks pregnant and more rolls. If you’re concerned about your baby’s movements, contact your healthcare provider for more advice.
