Pregnancy Week 22 is an exciting stage of the second trimester. Your baby continues to grow and develop, while your body adapts to the increasing size of your uterus.
At this stage, fetal movements may become easier to recognize. Your baby's senses and nervous system are also continuing to mature, and important developments are taking place in the brain, lungs and other organs.
You may also notice that your pregnancy bump is becoming more prominent and that some pregnancy symptoms are changing.
What Happens During Pregnancy Week 22?
During Week 22, your baby continues gaining length and developing stronger muscles and bones.
The nervous system is becoming increasingly organized, helping your baby coordinate movements.
Your baby's sensory development also continues, including hearing and touch.
The placenta remains an important connection between you and your baby, providing oxygen and nutrients through the umbilical cord.
How Big Is the Baby at Week 22?
Your baby is approximately the size of a papaya, although exact measurements vary.
The baby's body continues gaining weight and becoming more proportioned.
Growth will continue rapidly throughout the remainder of the second trimester and into the third trimester.
Baby's Movement at Week 22
Your baby's movements may now be more noticeable.
You may feel:
- Kicking
- Stretching
- Rolling
- Turning
- Gentle tapping
- Repeated movements
Your baby may also have periods of activity followed by periods of rest.
At this stage, movement patterns are still developing, so they may not yet follow a predictable routine.
Baby's Developing Senses
Your baby's sensory systems continue developing.
The brain is processing signals from different parts of the body, while the senses of hearing, touch and taste continue maturing.
These developments help prepare your baby for life outside the uterus.
Baby's Hearing
The baby's hearing system continues becoming more developed.
Your baby can hear sounds from inside your body, such as your heartbeat and breathing.
As pregnancy progresses, sounds from the outside environment may also become more noticeable.
Talking or reading to your baby can be a pleasant bonding activity.
Baby's Skin
Your baby's skin remains delicate and may appear wrinkled because there is still relatively little fat underneath it.
The skin is protected by vernix caseosa, a creamy coating that helps protect it from the surrounding amniotic fluid.
Fine hair called lanugo may also remain on the baby's body.
Baby's Brain Development
The brain continues developing rapidly during this period.
Connections between nerve cells are becoming increasingly complex.
These changes support movement, sensory development and other important functions.
Brain development will continue throughout the rest of pregnancy and after birth.
Baby's Lungs
The lungs continue developing during Week 22.
Although they are not yet mature enough to function normally outside the uterus, important structures are developing in preparation for breathing after birth.
Lung development continues throughout pregnancy.
Pregnancy Symptoms During Week 22
You may experience:
- Increased appetite
- Heartburn
- Constipation
- Bloating
- Back pain
- Leg cramps
- Mild headaches

Some women feel energetic during this stage, while others experience increasing physical discomfort.
Your Growing Baby Bump
Your uterus continues expanding as your baby grows.
Your pregnancy bump may now be clearly visible.
Every pregnancy bump is different, so avoid comparing your appearance with another pregnant woman.
The size and shape of your abdomen can be influenced by your body type, previous pregnancies, muscle tone and the baby's position.
Back Pain During Week 22
The growing uterus can change your posture and place additional pressure on your back.
To improve comfort:
- Maintain good posture.

If you experience severe or persistent back pain, speak with your healthcare provider.

- Eat smaller meals.
- Eat slowly.
- Avoid foods that trigger symptoms.

Consult your healthcare provider before taking medication for heartburn.
Constipation
Pregnancy hormones can slow digestion, making constipation common.
To support healthy digestion:

Speak with your healthcare provider if constipation is severe or persistent.
