Pregnancy Week 29 is another important stage of the third trimester. Your baby continues to grow rapidly, gain body fat and develop stronger muscles, while the brain, lungs and nervous system become increasingly mature.

At this point, your baby's movements may feel quite strong. You may also notice that your body needs more rest as the growing uterus puts additional pressure on your stomach, bladder, back and other organs.

Taking care of your nutrition, hydration, sleep and emotional well-being remains important as you move closer to the final weeks of pregnancy.

What Happens During Pregnancy Week 29?

During Week 29, your baby continues gaining weight and developing body fat.

The brain is growing rapidly, and the nervous system is becoming more sophisticated.

The lungs continue developing, while the muscles and bones become stronger.

Your baby is also becoming increasingly responsive to sounds and other sensory experiences.

How Big Is the Baby at Week 29?

Your baby is approximately the size of a butternut squash, although exact measurements can vary.

The baby continues gaining weight throughout the third trimester.

As more body fat develops, the baby's skin gradually becomes smoother and less wrinkled.

Baby's Movement at Week 29

Your baby's movements may feel stronger than they did earlier in pregnancy.

You may notice:

Strong kicks
Punches
Rolling
Stretching
Turning
Hiccups
Short periods of increased activity

As your baby grows and the available space becomes more limited, the type of movement may gradually change from large rolls to more noticeable kicks, stretches and shifting.

You should still be able to feel your baby moving regularly.

Understanding Your Baby's Movement Pattern

By Week 29, it is helpful to become familiar with your baby's usual pattern of movement.

There is no universal number of movements that every baby should make.

What matters is noticing what is normal for your baby.

If you notice a significant reduction or clear change in your baby's usual movements, contact your maternity care provider promptly.

Baby's Brain Development

The brain continues undergoing rapid development.

The surface of the brain becomes increasingly complex, and connections between nerve cells continue forming.

These changes support movement, sensory processing and other developing abilities.

Brain development continues throughout pregnancy and after birth.

Baby's Hearing

Your baby's hearing continues to mature.

Your baby can hear your heartbeat, breathing and other internal sounds.

External sounds may also reach the baby.

Talking, reading or singing to your baby can be a relaxing bonding activity.

Baby's Eyes

Your baby's eyes continue developing.

The eyelids can open and close, while structures involved in vision continue maturing.

The baby's vision is still immature, but eye development continues during the remainder of pregnancy.

Baby's Lungs

The lungs continue to mature during Week 29.

Important structures involved in breathing are developing, but the lungs are still immature.

Lung development continues throughout the third trimester.

Baby's Skin and Body Fat

Your baby continues developing more fat beneath the skin.

This gives the body a fuller appearance and will eventually help with temperature regulation after birth.

Vernix caseosa continues protecting the skin from the surrounding amniotic fluid.

Some lanugo may still be present.

Pregnancy Symptoms During Week 29

You may experience:

Heartburn
Constipation
Bloating
Back pain
Pelvic discomfort
Leg cramps
Increased appetite
Breast tenderness
Increased vaginal discharge
Mild swelling
Difficulty sleeping
Increased tiredness
Occasional headaches
Shortness of breath
Frequent urination

Symptoms can vary significantly between pregnancies.

Your Growing Baby Bump

Your uterus continues expanding as your baby grows.

You may notice that your abdomen feels heavier and that some movements require more effort.

You may also need to urinate more frequently because the growing uterus can put pressure on your bladder.

Try to take regular breaks and avoid standing for long periods if it makes you uncomfortable.

Back and Pelvic Discomfort

The growing uterus can change your posture and place additional pressure on your lower back and pelvis.

To improve comfort:

Maintain good posture.
Avoid heavy lifting.
Wear comfortable supportive shoes.
Change positions regularly.
Use pillows for support while sleeping.
Take gentle walks if appropriate.
Practice pregnancy-safe stretching.

Contact your healthcare provider if pain becomes severe, persistent or is accompanied by other concerning symptoms.

Heartburn During Week 29

Heartburn may become more noticeable during the third trimester.

You can try:

Eating smaller meals.
Eating slowly.
Avoiding foods that trigger symptoms.
Remaining upright after eating.
Avoiding large meals before bedtime.

Speak with your healthcare provider before using medication for heartburn.

Constipation

Constipation can continue because pregnancy hormones can slow digestion.

Helpful habits include:

Drinking enough water.
Eating fruits and vegetables.
Choosing whole grains.
Including fiber-rich foods.
Staying active if appropriate.

If constipation becomes severe or persistent, consult your healthcare provider.

Leg Cramps and Swelling

Leg cramps can occur during the third trimester.

Gentle stretching and regular movement may help.

Mild swelling of the feet and ankles can also be normal during pregnancy.

However, sudden or significant swelling, especially when accompanied by severe headache, vision changes or upper abdominal pain, requires prompt medical attention.

Breast Changes

Your breasts continue preparing for breastfeeding.

You may notice:

Increased fullness
Tenderness
Darker areolas
More visible veins

A supportive maternity bra can help improve comfort.

Exercise During Week 29

For many women with uncomplicated pregnancies, moderate physical activity can be beneficial.

Suitable activities may include:

Walking
Swimming
Prenatal yoga
Light strength exercises
Gentle stretching

Avoid activities with a high risk of falling or abdominal injury.

Follow your healthcare provider's recommendations if you have been advised to restrict physical activity.

Sleep During Week 29

Sleeping may become more difficult as your belly grows.

Pillows can support your abdomen, back or legs and may make sleeping more comfortable.

Try to maintain a regular bedtime routine and give yourself enough time to rest.

If persistent sleep problems are affecting your daily life, speak with your healthcare provider.

Prenatal Care

Regular prenatal care is especially important during the third trimester.

Your healthcare provider may monitor:

Blood pressure
Weight
Pregnancy symptoms
Baby's growth
Blood tests
Urine tests
Medications
Prenatal supplements

Depending on your individual circumstances, additional tests or screenings may be recommended.

Preparing for Birth

As your due date gets closer, you can begin preparing gradually.

Consider:

Learning about labor and delivery.
Discussing your birth preferences with your healthcare provider.
Preparing a list of important phone numbers.
Organizing baby essentials.
Thinking about transportation to your maternity unit.
Discussing who will support you during labor.
Preparing for the first days after birth.

You do not need to have everything completed immediately.

Emotional Well-Being

The third trimester can bring excitement as well as anxiety.

You may be thinking more about labor, delivery, parenting and your baby's health.

Talking with people you trust can help you process these emotions.

Make time for rest and activities that help you relax.

If persistent anxiety or sadness interferes with your daily life, speak with a healthcare professional.

Contact your healthcare provider promptly if you experience:

Heavy vaginal bleeding
Severe abdominal or pelvic pain
Severe persistent one-sided pain
Fainting
Significant dizziness

Conclusion

Pregnancy Week 29 is a period of continued rapid growth and development. Your baby is gaining body fat, becoming stronger and developing increasingly mature brain, lung and nervous-system functions.

Fetal movements may feel stronger and may gradually change as your baby grows and space inside the uterus becomes more limited.
