The fetus at 19 weeks of gestation is about 15 cm long and weighs between 200-250 g. The development of the fetus is related to congenital genetics and maternal nutrient supply. 19 weeks of gestation is a small fetus, but the sensory organs are differentiating, such as nerve cells for vision, touch and taste. The fetus is already moving and the fetal heart sounds can be monitored by a fetal heart stethoscope. Hair begins to grow and gender can be identified from the external genital organs. There is already respiratory movement and swallowing function, and can swallow amniotic fluid. This is a rapid period of fetal growth and development. It is important to have a balanced diet with more protein-rich foods, such as milk, eggs and meat, and more fresh fruits and vegetables to provide rich vitamins and promote the development of the body’s bones, in addition to regular maternity checks during pregnancy.
