What is developing at 23 weeks

Your baby's hearing continues to sharpen, and louder sounds from the outside world, such as your voice, your heartbeat, and everyday noise, come through more clearly. Skin is still a little translucent and wrinkled, but baby is steadily putting on fat to fill it out. Blood vessels in the lungs are developing in preparation for breathing after birth.

Your body

What you may be feeling

You may notice your feet and ankles swelling, especially at the end of the day. Mild and irregular tightening called Braxton Hicks contractions can begin around now, which is your uterus practicing. Braxton Hicks are irregular and usually painless. If tightenings become regular, painful, or come more than about six times an hour, or if you have low back pressure, fluid leaking, or bleeding, call your provider right away. Some women experience changes in skin pigmentation, including darker patches on the face known as the mask of pregnancy.

Tips for week 23

Talk, sing, or read to your baby, since hearing your voice now can be soothing and helps you bond. Elevate your feet and stay hydrated to help manage swelling, and contact your provider if swelling becomes sudden or severe. Wearing a brimmed hat and sunscreen can help reduce darker skin patches.
