Pregnancy Week 24 is an important stage of the second trimester. Your baby continues to grow and become stronger, while the brain, lungs, nervous system and sensory organs continue developing.

You may now be noticing your baby's movements more clearly. Your uterus is also continuing to expand, which can cause changes in your posture, sleep and digestion.

Although pregnancy may feel increasingly noticeable, every woman experiences this stage differently.

What Happens During Pregnancy Week 24?

During Week 24, your baby's body continues developing and gaining weight.

The muscles are becoming stronger, allowing more noticeable movements. The nervous system is also becoming more organized, helping coordinate movement and sensory responses.

The lungs continue developing in preparation for breathing after birth.

The placenta continues supplying your baby with oxygen and nutrients through the umbilical cord.

How Big Is the Baby at Week 24?

Your baby is approximately the size of a cantaloupe, although exact measurements vary.

The baby continues gaining weight and gradually developing more body fat.

Growth will continue throughout the remainder of pregnancy.

Baby's Movement at Week 24

Your baby's movements may now be much easier to recognize.

You may feel:

Kicks
Punches
Rolling
Stretching
Turning
Repeated movements

Your baby also has periods of activity and rest.

As pregnancy progresses, you will gradually become more familiar with your baby's usual movement pattern.

Why Is Fetal Movement Important?

Movement is a normal part of fetal development.

It reflects the ongoing development of muscles, joints and the nervous system.

At this stage, movement patterns may still vary, but learning to recognize your baby's normal pattern becomes increasingly useful as pregnancy progresses.

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

Baby's Brain Development

The baby's brain continues developing rapidly.

Neural connections are becoming more complex, helping coordinate movement, sensory information and other developing functions.

The brain will continue undergoing major changes throughout the remainder of pregnancy and after birth.

Baby's Lungs

The lungs continue to mature during Week 24.

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

The baby's lungs will continue developing for many weeks before birth.

Baby's Hearing

Your baby's hearing continues to mature.

The baby can hear sounds from inside your body, including your heartbeat and breathing.

Sounds from outside the uterus may also be heard.

Talking, reading or singing to your baby can be a pleasant way to spend time together during pregnancy.

Baby's Skin

Your baby's skin remains relatively thin and delicate.

The skin is protected by vernix caseosa, a substance that helps protect it from prolonged exposure to amniotic fluid.

Fine hair called lanugo may continue covering parts of the baby's body.

As the baby develops more body fat, the appearance of the skin will gradually change.

Pregnancy Symptoms During Week 24

You may experience:

Heartburn
Constipation
Bloating
Back discomfort
Leg cramps
Increased appetite
Mild headaches
Breast tenderness
Increased vaginal discharge
Mild swelling
Stretching sensations around the abdomen
Difficulty sleeping

Not every pregnant woman experiences the same symptoms.

Your Growing Baby Bump

Your uterus continues expanding as your baby grows.

Your pregnancy bump may now be very noticeable.

The size and shape of your abdomen can vary depending on your body type, previous pregnancies, muscle tone and baby's position.

A different-looking bump does not necessarily indicate a problem.

Back Pain During Week 24

Your growing uterus can alter your posture and put additional pressure on your back.

You can improve comfort by:

Maintaining good posture.
Avoiding heavy lifting.
Wearing comfortable supportive shoes.
Changing positions regularly.
Using pillows for support while sleeping.
Practicing gentle stretching if appropriate.

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

Heartburn During Pregnancy

Heartburn can become more common as pregnancy progresses.

You may find it helpful to:

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

Ask your healthcare provider before taking any medication for heartburn.

Constipation

Pregnancy hormones can slow digestion.

To support regular bowel movements:

Drink enough water.
Eat vegetables and fruits.
Choose whole grains.
Include other fiber-rich foods.
Stay active if appropriate.

If constipation becomes severe or persistent, speak with your healthcare provider.

Leg Cramps and Swelling

Leg cramps can occur during pregnancy.

Gentle stretching, regular movement and adequate hydration may help.

Mild swelling of the feet and ankles can also occur, especially after standing for long periods.

However, sudden or significant swelling, particularly when accompanied by a 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 and comfortable bra can help reduce discomfort.

Exercise During Week 24

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

Suitable activities may include:

Walking
Swimming
Prenatal yoga
Light strength training
Gentle stretching

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

If your healthcare provider has recommended exercise restrictions, follow their advice.

Sleep During Week 24

As your belly becomes larger, sleeping may become more difficult.

Pillows can help support your abdomen, back and legs.

Try to maintain a relaxing 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

Continue attending your regular prenatal appointments.

Your healthcare provider may monitor:

Try to maintain supportive relationships and give yourself time to rest.

Relaxation, gentle physical activity and talking with people you trust may help.

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

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