Pregnancy

• Pregnancy at 9 Weeks: Weekly Calendar

  This week, your baby’s muscles are developing. Your little one may even start moving, but you won’t feel it yet!

• Pregnancy Calendar: Week 14

  Some fine hairs, called lanugo, have developed on your baby’s face. This soft colorless hair protects the skin and will eventually cover most of your baby’s body until it is shed just before delivery.

• Pregnancy Calendar: Week 15

  Muscle development continues, and your baby is probably making lots of movements with his or her head, mouth, arms, wrists, hands, legs, and feet.

• Pregnancy Calendar: Week 17

  Your baby is still very tiny at about 5.1 inches from crown to rump this week.

• Pregnancy Calendar: Week 18

  Your baby’s bones had been developing but were still soft. This week, they begin to harden, or ossify.

• Pregnancy Calendar: Week 19

  A waxy substance called vernix caseosa is covering your baby to help protect the delicate skin from becoming chapped or scratched.

• Pregnancy Calendar: Week 21

  Your baby’s intestines are developed enough that small amounts of sugars are absorbed from the fluid your baby swallows and passed through the digestive system to the large bowel.

• Pregnancy Calendar: Week 22

  Brain and nerve endings are formed enough so that the fetus can feel touch, while you might be feeling irregular, painless Braxton Hicks contractions.

• Pregnancy Calendar: Week 23

  You may feel more forceful movements — your baby’s daily workout routine includes moving the muscles in the fingers, toes, arms, and legs.

• Pregnancy Calendar: Week 24

  Your baby’s inner ear has developed enough that your baby can know when he or she is upside down or right side up in your belly.
