After checking the size of your belly to make sure your doctor or midwife has predicted the right gestational age of the baby, the sonographer will look at things like the volume of amniotic fluid, the anatomy of the brain and heart, the face, kidneys, limbs, bones, and the blood vessels in the umbilical cord to make sure they're all developing healthfully.
