Third Trimester

Third trimester (weeks 25 to birth)

In your third trimester, your body is preparing to give birth. Both your baby and you are gaining weight.

By your due date, it’s normal to weigh 25 to 35 pounds more than you did before pregnancy (due to your baby’s weight and that from the placenta, amniotic fluids, enlarged breasts, uterus, and increased blood and fluid volumes).

You may experience some discomfort during this stage, but you’re almost there!

Tasks

What should I do to prepare?

  • Select a pediatrician or family doctor for your baby by viewing the profiles at kp.org/doctorsandlocations.
  • Schedule a visit to meet your baby’s future doctor.
  • Tour and pre-register with your delivery hospital (Northside or Emory Decatur Hospital).
  • Finish your nursery and purchase baby essentials.
  • Install your car seat.
  • Pick up your breast pump at your 36- to 38-week visit (if eligible).
  • Make a note in your calendar to add your newborn to your Kaiser Permanente health plan within 31 days of birth.
  • Pack your hospital bag.

Your prenatal appointments

Around your 32-week visit, your practitioner will talk with you about the results of your tests for anemia, diabetes, and Rh blood factor (if you have an Rh-negative blood type). He or she will also check your baby’s growth, review the early warning signs of labor, and talk to you about choosing a doctor for your baby.

Tour and pre-register with your delivery hospital

When it comes time for delivery, you’ll see the Kaiser Permanente health care team on call at the hospital that’s paired with the doctor’s office you’ve selected for prenatal appointments.

For most low- or normal-risk pregnancies, our midwives are there to help deliver your baby. Should your labor deviate from normal, the physician on call will provide immediate attention.

We partner with two top Atlanta hospitals where we have Kaiser Permanente doctors and certified nurse midwives on staff: Northside Hospital and Emory Decatur Hospital.

The hospital where you’ll deliver is based on the home office you select for your routine pregnancy appointments.

Discuss timely hospital discharge and home visit/virtual visit with your doctor or midwife

How long you stay in the hospital after your baby is born will depend on your health and the health of your baby. If you’ve had a healthy, uncomplicated delivery and you are stable, your doctor or midwife will likely discharge you from the hospital a day after a vaginal delivery or two days after a cesarean section, with complimentary in-home care the next day.

During the visit, a certified registered nurse will care for you and your baby in the comfort of your home. Click here to learn more about timely hospital discharge and home visit service.

At the hospital, you’ll have much to do before you go home with your new baby. A physical exam will be completed to ensure that you are ready to go home.

A physical exam will be completed to ensure that your baby is healthy enough to go home. Here are a few items your care team at the hospital will check for:

  • Hepatitis B vaccine: Your newborn should receive the hepatitis B vaccine while in the hospital. This vaccine should not be postponed until after discharge. It is given to safeguard against transmission of this virus from mother and other caregivers to the newborn and is most effective if given shortly after delivery. Receiving the hepatitis B vaccine can prevent your infant from developing chronic hepatitis B infection, which is the leading cause of liver cancer worldwide.
  • Vitamin K: A single dose of vitamin K will be given to your newborn to reduce the risk of a rare but sometimes fatal bleeding disorder which can occur during the first 6 months of life.
  • Erythromycin eye ointment: A single dose of erythromycin eye ointment will be applied to your newborn’s eyes to reduce the risk of certain eye infections which could potentially cause eye damage and blindness.
  • Oxygen screen: Your newborn will have an oxygen screen to check for certain types of heart disease.
  • Metabolic screen: A newborn metabolic screen will be performed. This is a blood test to detect inherited disorders that may have no symptoms early in life but can cause significant illness if not identified and treated early.
  • Hearing screen: Your newborn will have a hearing screen. If the hearing screen is failed, a repeat test will be scheduled after discharge at a Kaiser Permanente medical office.
  • Tdap and flu vaccines for the family: The Tdap vaccine and the flu vaccine are recommended for all family members who are caretakers for the member. These vaccines can be given to the mother in the hospital if not already received.

Breastfeeding Support

Kaiser Permanente offers many breastfeeding resources, such as our one-on-one breastfeeding classes and the Lactation support line. Learn more about the resources available to you here.

Week 36–38 visit: Pick up your breast pump (if eligible)

If you’re planning to breastfeed and want to express and store your milk, you’ll need a breast pump. You can learn about breast pumps in our health classes or by asking one of our lactation consultants.

If your insurance provides breast pump coverage and you have not yet received your breast pump, you or a family member can pick one up at the office where you regularly receive your OB care during normal department operating hours.

You will need your Kaiser card and photo ID to obtain the breast pump. Your breast pump must be picked up within 6 months of your baby’s birth.

Pack your hospital bags!

Don’t wait until your first labor pains to get ready to go to the hospital. Pack your bag at least 3 weeks before your due date with these items.

For you:

  • Kaiser Permanente ID card
  • Toiletries (toothbrush, toothpaste, lip balm, brush, hair clip or band, lotion, cosmetics)
  • Nightgown and/or robe (if you prefer to wear your own)
  • Nonskid slippers
  • Hand fan or spray mist bottle
  • Underwear
  • Supportive bra or nursing bra (for breastfeeding mothers)
  • Comfortable, loose–fitting clothing to wear home
  • Relaxing music or audio programs
  • A camera and charger
  • Cell phone and charger
  • Eyeglasses and contact lens supplies
  • Snacks, a change of clothes, and toiletries for your partner
  • An extra bag or tote for any additional items you receive at the hospital

For baby

  • Infant safety seat (required by law to be in the car when you leave the hospital)
  • Outfit for going home (undershirt, outer garment, hat, depending on the weather)
  • Receiving blankets
  • Mittens (many babies have long fingernails and can scratch their faces)

Your body

As your third trimester begins, new symptoms may arise: aching back, leg cramps, minor swelling, and sleep problems, to name a few. Continue to get moderate exercise, which can help prevent and relieve some of these symptoms.

Feel as if you can’t catch your breath? It’s your growing uterus pressing up on your diaphragm and crowding your lungs. As you enter the final months of your pregnancy, the fatigue that you felt during the first trimester may return as your body grows larger and sleep becomes more difficult.

Towards the end of your pregnancy, breathing might become a little easier as the baby drops into the pelvis in preparation for birth (called “lightening”). Your cervix will begin to thin out (efface) and open (dilate) by the time you go into labor. For some women, these changes begin weeks before their due date as their bodies prepare for labor and birth.

At 37 weeks, your baby does not have much room to move around, so you will probably notice less big movement than before. Though your baby will not be full-term until 39 weeks, labor could begin at any time.

If your pregnancy goes beyond 41 weeks, your provider may order tests to determine whether to induce labor or continue to wait to for your baby to come on his or her own. Inducing labor can increase your chance of needing a cesarean section.

What’s normal

  • Your blood pressure may increase slightly, returning to its normal pre–pregnancy state.
  • Sometimes your baby settles into a position that is uncomfortable for you. Kicks and twists can be strong, very noticeable, and sometimes painful.
  • You may feel pelvic pressure or pain if your baby’s head is low in the pelvis. Lying on your side may help relieve this discomfort.
  • Your feet, ankles, hands, and fingers may become swollen, particularly at the end of the day. It’s normal to have extra fluid in your tissues during pregnancy, but much of the swelling should disappear after a good night’s sleep.
  • As your growing uterus puts pressure on your bladder, you might notice that you leak urine when you laugh or cough. This is common and is called urinary incontinence. If you notice any consistent leaking, whether it is a large or small amount, call your doctor’s office to make sure that your water hasn’t broken.
  • Your growing uterus is also crowding other surrounding organs, leading to many common discomforts and annoyances, including heartburn, constipation, and hemorrhoids.
  • You’re likely making frequent trips to the bathroom.
  • Leg cramps, breathlessness, contractions, the frequent need to urinate, and an active baby may all interfere with your sleep.
  • Feel aching or numbness in your fingers, wrists, or hands? You may have carpal tunnel syndrome.
  • You’ve probably noticed how easy it is to get off balance and feel clumsy as your pregnancy has progressed. This is partly due to your center of gravity moving forward as your baby grows. You also release a pregnancy hormone called relaxin that softens the cartilage in your joints and pelvis. The pubic bone opens up to make more room for the baby, causing the “pregnancy waddle” that many women have when they walk.

Your baby

Weeks 25–28

Your baby’s eyes are able to open and close, skin is becoming smooth, and hair is getting longer. The lanugo, a soft, fine downy hair that once covered your baby, is beginning to disappear. The vernix caseosa, a white creamy substance that protects the skin from long exposure to amniotic fluid, still covers your baby’s body. The lungs are maturing, and your baby is starting to practice breathing. In your seventh month, your baby continues to put on a lot of weight. By the end of week 28, your baby weighs about 2 to 2.5 pounds and measures about 11 to 14 inches long.

Weeks 29–32

Your baby’s brain and vision are developing very quickly now. The bones are fully developed, but still soft and flexible for delivery. Your baby’s fingernails and toenails are growing, lungs are maturing, and the nervous system is almost complete. Your baby is also starting to develop taste buds and can taste sweet and sour. By week 32, your baby is probably in the head–down position and is taking up more and more space in your uterus. Your baby weighs about 3 to 5 pounds and measures about 16 to 18 inches long.

Weeks 33–36

Your baby is busy preparing for life outside the womb by storing iron in his or her liver. Things have become crowded inside your uterus, and there’s not as much room for your baby to move around. Your baby’s skin is now pink and smooth, and the arms and legs look chubby. Bones in his or her head are firm but flexible enough to pass through the birth canal without damage. The vernix caseosa is disappearing. The lanugo is almost completely gone except for some soft, fine hairs on your baby’s back and shoulders. During this final month, your baby’s lungs are almost fully developed. By week 36, your baby weighs about 5 to 7 pounds and measures around 18 to 20 inches from head to heels.

Weeks 37–birth

Your baby’s basic physical development is now complete. He or she will start to move down into the pelvic cavity around week 38 (a process called engagement). The lungs are now mature, and your baby is practicing for his or her first breath of air. The umbilical cord is 20 inches long and will support baby through birth until the lungs take over. Your baby will spend the next few weeks putting on weight. At birth, most full–term babies weigh between 6 pounds and 9 pounds and measure 19 to 21 inches long. But healthy babies come in many different shapes and sizes.
