Pregnancy Week by Week

Pregnancy Week by Week: 14 Weeks Pregnant

At this point in your pregnancy, your baby is about 3.2 to 4.5 inches long and weighs about 1 ounce. While the sex of your baby was determined when the egg was fertilized by the sperm, by week 14 of pregnancy, your baby's sex organs have fully differentiated into male or female.
 
Other fetal developments include the following:
 
  • The ears have moved from the neck onto the head
  • The thyroid gland starts to produce hormones
  • The baby begins to practice inhaling and exhaling
  • The baby's chin no longer rests on his or her chest
  • For boys, the prostate gland is developing
  • For girls, the ovaries move from the abdomen into the pelvis
  • The hands are becoming functional.
 
Your pregnancy hormones should be leveling off this week, which means that you should be experiencing less nausea, less frequent urination, and less exhaustion.
 
Changes occurring in your body during this week of pregnancy may include the following:
 
  • The veins on your chest and breasts may become more dilated.
 
  • The areolas (the darker, colored part around your nipple) of your breasts are darkening and growing larger in diameter.
 
  • Your body is preparing for breastfeeding by growing new milk ducts. Your breasts may become larger, heavier, lumpy, and sore. Also, the nipple area may become more sensitive to touch.
