Your baby’s body is now beginning to resemble that of a tiny human! Muscles, bones, fingers, and a small nasal button are forming. At this stage, your baby measures about 16 mm, about the size of a blueberry.
The lungs are starting to develop, and the retinas of the eyes are forming, which will later determine eye color. The brain continues to grow rapidly, and the tail has now fully disappeared.
The foot buds are developing into toes, and both arms and legs are growing. The upper limbs are currently longer and more developed than the lower ones and the baby can already bend and move their arms; because the upper body growth is faster than the lower one.
Taste buds and a nasal button are also developing, and the umbilical cord is now fully formed. The genitals are beginning to take shape, and the upper lip and eyelids are forming. The baby’s abdomen and the surrounding amniotic fluid are growing, which causes your uterus to expand.
