Pregnancy Week 22

When you are 22 weeks pregnant, your baby is about 7.6 inches long and weighs about 12.3 ounces. Your baby may now respond regularly to sound, rhythm, and melody. Additional fetal development taking place includes the following:
  • The liver is starting to break down bilirubin, which is a substance found in red blood cells. Once broken down by the liver, bilirubin is removed from the body through the intestines.
  • Taste buds have started to form on the tongue.
  • Brain and nerve endings are formed enough so that the fetus can feel touch.
You may notice that your uterus starts practicing for delivery with irregular, painless contractions. These are known as Braxton Hicks contractions and are not dangerous or harmful. However, if the contractions become painful, or if you have more than four contractions in an hour, contact your healthcare provider immediately.
In week 22 of your pregnancy, you may experience low back pain and cramping in the legs and feet. To reduce cramping, increase your intake of calcium and potassium. Good sources of calcium include:
  • Milk
  • Yogurt
  • Cheese.
You can find potassium in foods such as:
  • Grapefruits
  • Oranges
  • Bananas.
