Development of the Baby at 21 Weeks
At this stage, your baby is about 10.5 inches long, crown to rump, and weighs around 12.7 ounces. Your baby’s skin is still translucent, and you can see the blood vessels through it. However, it will become more opaque as the baby grows. Your baby’s digestive system is also developing, and they are swallowing small amounts of amniotic fluid, which helps to develop the digestive system.
Your baby’s movements are more coordinated now since their nervous system is maturing. They are kicking and stretching, and you may start feeling those movements soon. Their lungs are also developing, and they are starting to produce a substance called surfactant, which helps the lungs to expand and function properly after birth.
Your baby is also developing their sense of touch. They are exploring their surroundings by touching their face and body with their hands. Their sense of hearing is also improving, and they can hear your voice and other sounds outside the womb. This is why it’s essential to talk to your baby and play music for them.
Changes in Your Body
Your body is also changing as your pregnancy progresses. Your uterus is now about the size of a cantaloupe, and you may start experiencing Braxton Hicks contractions. These contractions are usually painless and help to prepare your body for labor.
You may also notice that your breasts are leaking a yellowish fluid called colostrum. This is the first milk that your baby will receive after birth. Your body is getting ready to feed your baby, so it’s essential to wear nursing pads to prevent any embarrassing leaks.
You may also experience some discomfort in your back, legs, and hips. This is due to the hormone relaxin, which is produced during pregnancy, causing your ligaments and joints to loosen. It’s essential to practice good posture and do some light exercises to ease the discomfort.
What to Expect at Your 21-Week Ultrasound
At 21 weeks, you’ll have your mid-pregnancy ultrasound. This is an essential scan that checks your baby’s growth and development. Your healthcare provider will measure your baby’s head, abdomen, and thigh bone to ensure that they are growing correctly.
The ultrasound will also check your baby’s organs, including the heart, kidneys, and brain. Your healthcare provider will be able to see your baby’s gender at this stage if you choose to find out.
