Your baby at 29 weeks
Your Baby Is Building Fat Under the Skin
At 29 weeks, your baby is starting to store white fat under the skin.
What is happening this week
Your baby is often about 38–39 cm (15–15.4 in) long and weighs around 1,250 g (2.8 lb). White fat begins to build up under the skin, which helps the baby stay warm and keep up energy after birth.
- Fat gradually makes the body look rounder.
- The skin looks less see-through, and body outlines become softer.
- The brain, muscles, and senses continue to develop.
How this week may feel
Many people notice stronger movements and a growing belly at 29 weeks. Heartburn, swelling, back pain, and evening tiredness are common.

Why Your Walk Changes at 29 Weeks
Your Walk May Be Changing, and That Is Common
At 29 weeks, many pregnant people notice that their usual movements feel different. You might feel less steady on your feet or notice that you are standing or walking with your feet a bit wider apart. These changes are common and are usually part of how your body adapts to pregnancy.
The Role of Hormones: Softer Ligaments
A hormone called relaxin is one reason for these changes. It helps loosen the ligaments and joints, especially in the pelvis. This added flexibility may help the pelvis make room for birth.
Center of Gravity and Balance
As your baby grows, your center of gravity moves forward. Your body often adjusts your posture and how you place your feet to help you stay balanced. This can make your walk look different, sometimes described as more of a waddle. Be extra careful on wet or uneven surfaces, and use handrails on stairs.
When to Contact Your Provider
Common symptoms at 29 weeks
Your growing uterus presses up on your diaphragm, so a deep breath may feel harder to get. Sitting up straight, taking breaks, and moving slowly can make it feel easier.
Hormones relax the valve between your stomach and esophagus, and a full stomach pushes acid upward. Smaller meals, staying upright after eating, and avoiding late-night snacks often help.
Cramps in the calves, often at night, are common this late in pregnancy. Gently stretching your calf before bed and staying hydrated may ease them.
Extra fluid in the body can cause mild swelling, especially after standing for a long time. Resting with your feet raised and wearing supportive shoes may help, and sudden swelling in the face or hands is worth reporting to your care team.
Your belly may tighten for a bit and then relax, without a steady pattern. Changing position, drinking water, or resting often helps these tightenings pass.
Relaxin loosens the joints around your pelvis, which can cause aching or pressure in the hips and groin. Supportive pillows between your knees in bed and gentle movement may bring some relief.

Tests and appointments
- Glucose screening. A blood test or drink test, usually offered between 24 and 28 weeks, checks for gestational diabetes if it has not been done yet.
- Tdap vaccine. This vaccine helps protect your baby from whooping cough, and it is commonly given in the late second or third trimester.
- Rh blood test and RhoGAM. If your blood type is Rh-negative, your care team may offer RhoGAM around 28 weeks to protect your baby's blood.

Why does my hip hurt when I walk at 29 weeks?
Relaxin loosens the joints in your pelvis, and your weight shifts as the baby grows. This can cause hip or groin aching. Gentle stretching, supportive shoes, and rest often help. Let your care team know if the pain is severe or comes with other symptoms.
How often should I feel my baby move at 29 weeks?
Many care teams suggest tracking movements daily and noticing your baby's normal pattern. Changes in how often your baby moves are worth sharing with your care team, even if you are unsure.
Is it normal to feel short of breath at 29 weeks?
Yes, it is common because your growing uterus pushes against your diaphragm. Sitting upright and pacing activities can help. Contact your care team right away if you have chest pain, trouble breathing at rest, or a sudden cough.
