In the fetus at the 2nd month of pregnancy, the brain, excretory and respiratory systems are actively developing, the rudiments of joints appear, and the bones of the skeleton begin to form. During this period, the limbs develop rapidly, facial features become clearer, the eyes, which were previously located almost on the sides of the head, approach each other, and even the rudiments of milk teeth appear. The fetus is already making various movements, but you can feel it a little later.
The size of the fetus in the second month of pregnancy is about 2 cm.
