** Gestational age is the age of the pregnancy from the last normal menstrual period (LMP) and fetal age is the actual age of the growing baby.
If your baby were delivered now, it could survive with the assistance of medical technology. The fetus has developed sleeping and waking cycles and mom will begin to notice when each of these takes place. The fetus has a startle reflex and the air sacs in the lungs have begun formation. The brain is developing rapidly over the next few weeks. The nervous system has developed enough to control some functions. The length of the fetus has reached about 14 inches and weighs about 2 ΒΌ lbs.
