Your Baby's Development
Your baby is constantly adapting to life inside the uterus. By this week, the umbilical cord has formed. It will be your baby’s connection to you throughout your pregnancy, providing oxygen and nourishment for your baby and disposing of your baby's wastes. In addition, your baby's digestive tract and lungs continue to form.
Are you waiting impatiently to see your baby's face on his or her birth day? You have a long way to go until then, but in the meantime, your baby's face is taking shape. The mouth, nostrils, ears, and eyes are some of the facial features that become more defined this week.
Dreaming of a son or daughter to play ball with? The arm bud that developed just last week has a hand on the end of it, which looks like a tiny paddle.
Pregnancy causes many changes in your cervix. By this week you'll have developed a mucous plug, which forms in the opening of the cervical canal and seals off the uterus for protection. (Eventually you'll lose this plug as your cervix dilates in preparation for labor.)
