The biggest highlight of this period is the development of the fetal brain. By the end of the 15th week, the fetus’s kidneys start to function and fetal urine is excreted into amniotic fluid. The adrenal glands develop and produce hormones that keep the baby’s hormonal balance.
By the end of the 16th week, the head of the baby is usually covered with fine hair. The baby’s nails are formed and his limbs move briskly. Starting with this period, a future mom may begin to feel her baby move. If you haven’t felt yourself a mother yet, it’s quite likely that after these first movements inside you, the significance of the motherhood will dawn on you.
A baby’s first movements may feel like a little fish swimming around. These movements feel also like muscle spasms. An increased fetal activity can be a sign of oxygen deficiency, or that the woman has too much of physical or mental activity. In the latter case, you need to get some fresh air and stroll to let your limbs stretch.
If there is no sign of the baby’s movements in due time, it’s time to see your doctor. Your baby’s movements are the sign of him being alive and developing well. The functioning of the body is managed by the endocrine system and central nervous system. The fetal cerebral hemispheres are formed and continue to develop. By the end of the 17th week, the baby starts to screw up his face and open his eyes briefly. At the beginning of the 18th week, the developing immune system starts to produce interferon and immunoglobulin. By the end of the 4th month the fetus is about 13 cm long!
