What Is Happening To Your Body
During this week of pregnancy, the hormonal changes in your body are becoming more apparent. In addition to the linea nigra (the dark line from your abdomen to your pubic bone), the areola (dark part of your nipple area) may have gotten darker and larger. This is normal as your body readies itself for your baby and breastfeeding.
What Is Happening To Your Baby
Your baby measures about 3.5 to 4 inches (8.9 to 10.2 cm) long from crown to rump, or roughly the length of a lemon. At this point your baby weighs about 1 ounce (28.4 grams).
The baby has also started secreting hormones of its own from its matured thyroid gland.
Your baby also continues to practice breathing the amniotic fluid through its lungs. In addition, he or she has developed soft nails on its fingers and toes. Your baby’s blood is also starting to form in its bone marrow and blood vessels. Its hands continue to develop as well and are becoming more functional.
As the eyes and ears continue to move into place, the baby’s mouth has gone through major development. The sucking muscles are growing strong and the salivary glands are almost fully developed. The esophagus, windpipe and larynx should all be present by the end of this week.
