14 Weeks Pregnant
When you're 14 weeks pregnant, your baby will start to get covered with a soft, fine hair over its body called lanugo. It is thought that this lanugo provides protection to the developing skin. The lanugo will be shed before he or she is born and replaced with thicker, coarser hair.
Speaking of he or she -- the baby is definitely a "he or she" now -- the sex organs are well defined at this point. 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 development that is occurring around week 14 of pregnancy includes the following:
- The ears have moved from the neck onto the head
- The digestive glands are complete
- The vocal cords are complete
- 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.
At 14 weeks pregnant, your baby is now receiving all of its nourishment from the placenta. The placenta has also taken over all hormone production from the ovaries. These hormones will continue to play a vital role in maintaining your pregnancy along with the changes in your body.
