Pregnancy Week 28 is an important milestone as you continue through the third trimester. Your baby is growing quickly, gaining body fat and becoming stronger, while the brain, lungs and nervous system continue to mature.

You may notice that your baby's movements are becoming more distinct. At the same time, your growing uterus can make sleep, digestion, movement and everyday activities more challenging.

This stage is a good opportunity to focus on regular prenatal care, healthy nutrition, rest and gradual preparation for the weeks ahead.

What Happens During Pregnancy Week 28?

During Week 28, your baby continues gaining weight and developing stronger muscles.

The brain is undergoing rapid development, while the nervous system is becoming better at coordinating movement and other functions.

The lungs are also continuing to mature.

Your baby is increasingly responsive to sounds and may have recognizable periods of activity and rest.

How Big Is the Baby at Week 28?

Your baby is approximately the size of an eggplant, although exact measurements vary.

The baby continues gaining weight as fat develops underneath the skin.

During the third trimester, your baby will continue growing and preparing for life outside the uterus.

Baby's Movement at Week 28

Your baby's movements may feel stronger and more obvious now.

You may notice:

Kicks
Punches
Rolling
Stretching
Turning
Hiccups
Short periods of increased activity

Your baby will also spend periods sleeping.

You may notice more movement when you are sitting or lying quietly because you are less distracted by your own activity.

Understanding Your Baby's Movement Pattern

By this stage, it can be useful to become familiar with your baby's usual pattern of movement.

There is no single number of movements that is considered normal for every pregnancy. What matters is becoming familiar with what is normal for your baby.

If you notice that your baby is moving significantly less than usual or there is a clear change in the normal pattern, contact your maternity care provider promptly.

Do not wait until the next appointment if you are concerned.

Baby's Brain Development

The brain continues to develop rapidly during Week 28.

The brain is becoming more complex, and connections between nerve cells continue to increase.

These developments support movement, sensory processing and other important functions.

Brain development continues throughout pregnancy and after birth.

Baby's Hearing

Your baby's hearing continues to mature.

Your baby can hear sounds from inside your body, including your heartbeat.

External sounds may also reach the baby.

You may enjoy talking, reading or singing to your baby as part of your pregnancy routine.

Baby's Eyes

Your baby's eyes continue developing.

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

Vision remains immature before birth, but eye development continues during the remainder of pregnancy.

Baby's Lungs

The lungs continue developing during Week 28.

The structures needed for breathing are becoming increasingly mature, but the lungs are still developing.

Lung maturation will continue throughout the third trimester.

Baby's Skin and Body Fat

Your baby is gradually gaining more body fat.

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

The skin remains protected by vernix caseosa, while some lanugo may still be present.

Pregnancy Symptoms During Week 28

Common symptoms may include:

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

Not every woman experiences all of these symptoms.

Your Growing Belly

Your uterus continues expanding as your baby grows.

Your abdomen may feel heavier, and you may find that bending, walking for long periods or getting comfortable in bed is more difficult.

Wear comfortable clothing and footwear, take regular breaks and avoid overexertion.

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.

Severe or persistent pain should be discussed with your healthcare provider.

Heartburn During Week 28

Heartburn can become increasingly common during the third trimester.

You may find it helpful to:

Eat smaller meals.
Eat slowly.
Avoid foods that trigger heartburn.
Stay upright after meals.
Avoid eating large meals immediately before bedtime.

Talk to your healthcare provider before taking medication for heartburn.

Constipation

Constipation can continue during pregnancy because hormonal changes can slow digestion.

Helpful habits include:

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

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

Leg Cramps and Swelling

Leg cramps are common during pregnancy.

Gentle stretching and regular movement may help.

Mild swelling of the feet and ankles can also occur.

However, sudden or significant swelling, particularly when accompanied by a severe headache, vision changes or upper abdominal pain, should be assessed promptly.

Breast Changes

Your breasts continue preparing for breastfeeding.

You may notice:

Increased fullness
Tenderness
Darker areolas
More visible veins

A comfortable supportive bra can help reduce discomfort.

Prenatal yoga
Light strength exercises
Gentle stretching

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

If your healthcare provider has advised you to limit exercise, follow their recommendations.

Pillows can support your abdomen, back and legs.

A consistent bedtime routine may also help you relax.

If persistent sleep difficulties are affecting your daily life, discuss them with your healthcare provider.

Prenatal Care

Regular prenatal appointments become increasingly important during the third trimester.

Your healthcare provider may monitor:

Pregnancy symptoms
Baby's growth

Organizing baby's sleeping area.
Learning about newborn care.
Discussing childbirth with your healthcare provider.

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

Talk with your partner, family, friends or healthcare provider about your concerns.

Make time for rest and activities that help you feel calm.

If anxiety or sadness becomes persistent or interferes with daily life, seek professional support.
