Your baby this week
Your baby is about 30cm long and weighs 600g. Your baby is gaining weight steadily, with most of the weight coming from accumulating baby fat, as well as from growing organs, bones, and muscle.
Your little one’s brain is growing rapidly at this time. The taste buds are also developing, and his/her footprints and fingerprints are continuing to form.
Your baby's lungs are becoming more developed and complex. The branches of the main lung are beginning to form as well as the special cells that will produce surfactant. Surfactant helps the air sacs to inflate easily once your baby reaches the outside world. Babies who are born prematurely usually have trouble breathing because these cells have not had enough time to develop or are not producing the necessary amounts of surfactant.
Your body this week
You should now feel the top of your uterus around 2 inches from your belly button. The skin on your abdomen and breasts are continuing to stretch. This can cause itchiness. If you are having itchy and/or dry skin, use a good oil based moisturizer or cream.
Most women have a glucose screening test between now and 28 weeks. This test checks for gestational diabetes. Women who have gestational diabetes, produce very large babies. This increases your risk of having a difficult vaginal delivery or needing a cesarean section because your baby has grown too large.
Other common pregnancy symptoms this week include:
- Lower abdominal pain
- Back pain
- Leg cramps
- Vision changes
- Swelling of ankles and feet
