Pregnancy Week 37 is an exciting milestone because you are now very close to meeting your baby. Your baby continues gaining weight and preparing for life outside the uterus.
Although your baby has developed significantly, important growth and maturation continue during the final weeks of pregnancy. The brain, lungs and other body systems continue developing.
You may notice increasing pelvic pressure, more frequent Braxton Hicks contractions, difficulty sleeping and a growing sense of anticipation as your due date gets closer.
What Happens During Pregnancy Week 37?
During Week 37, your baby continues to gain weight and body fat.
The brain and nervous system continue developing, while the lungs continue to mature.
Your baby's body is becoming more prepared to regulate temperature, feed and adapt to life after birth.
Your healthcare provider will continue monitoring your health and your baby's well-being during regular prenatal appointments.
How Big Is the Baby at Week 37?
Your baby is approximately the size of a winter melon, although exact measurements vary.
Your baby will continue growing during the coming weeks.
Every baby develops at a different rate, and your healthcare provider will assess growth based on your individual pregnancy.
Baby's Position at Week 37
Many babies are positioned head-down by this stage.
If your baby has moved lower into the pelvis, you may notice increased pressure in your pelvic area.
However, every pregnancy is different, and not all babies are in the same position at Week 37.
Your healthcare provider can check your baby's position during prenatal visits.
Baby's Movement at Week 37
Your baby's movements should continue to be noticeable.
You may feel:
- Strong kicks
- Stretching
- Pushing
- Turning
- Shifting
- Hiccups
- Pressure under your ribs
- Movement lower in your abdomen
Because there is less space inside the uterus, movements may feel different from earlier pregnancy.
You may notice fewer large rolls and more pushing or stretching movements.
However, you should continue paying attention to your baby's normal pattern.
Understanding Your Baby's Movement Pattern
Your baby still has periods of activity and sleep.
The important thing is to understand what is normal for your baby.
Do not assume that reduced fetal movement is normal simply because you are close to your due date.
If you notice a significant reduction or concerning change in your baby's usual movements, contact your maternity care provider promptly.
Baby's Brain Development
Your baby's brain continues developing rapidly.
Important connections between nerve cells continue forming.
These changes support movement, coordination, sensory processing and other important functions.
Brain development will continue after birth, especially during infancy and early childhood.
Baby's Lungs
Your baby's lungs continue maturing.
The respiratory system is becoming increasingly prepared for breathing after birth.
The final weeks of pregnancy continue to support lung and overall body development.
Baby's Body Fat and Skin
Your baby continues accumulating body fat.
This fat helps your baby regulate body temperature after birth.
The skin becomes smoother, and your baby's body develops a fuller appearance.
