How old is a four-month-old fetus?
At the fourth month of pregnancy, the fetal head is obviously more upright, and the eyes have moved to the front of the head. Of course, the eyes are still closed. However, during this period, we can see that the eyeball of the fetus can move, his eyebrows and eyelashes are growing rapidly, and his ears have reached the final position.
The skin of a four-month-old fetus is very thin and transparent, and blood vessels under the skin can be seen. The joints of the limbs have been formed and the bones have been further developed. At this time, the legs of the fetus have exceeded the length of the arms, the fingernails have been formed, and the joints can move.
During this period, the fetal sex organs are mature enough to distinguish sex, and of course, B-ultrasound can find out more. The fetus began to breathe with his chest, and he began to suck his thumb. The fetus had a fetal heart at this time. If mother is careful, she may feel the fetal movement.
The fetus that is pregnant for four months is still very small, just the size that can be put in the palm of your hand.
