Symptoms of pregnancy in week 21: The fetus can “hear”

During this period, the fetus\’s digestive organs are becoming increasingly developed. When the baby swallows amniotic fluid, a small amount of sugar can be absorbed by the intestines and then transported to the large intestine through the digestive system. Of course, almost all nutrients are still transported to your baby through the placenta. The secretion of fetal fat on the fetal body gradually increases, and the skin is smooth and tender. Vernix protects the skin of the fetus that remains in the amniotic fluid for a long time. The vernix secreted from the 20th week of pregnancy accumulates thickly on the eyebrows, making the eyebrows extremely soft. Fetal growth and development are now accelerated, especially the development of the brain. Not only does the weight increase, but the number of brain cells also begins to increase rapidly. At the same time, the fetal internal organs begin to differentiate, and organs such as the liver and kidneys begin to form. However, due to the strengthening of the functions of various fetal systems, the burden on pregnant mothers has also increased, and the demand and consumption have increased a lot. Physical Changes of Pregnant Mothers Nowadays, pregnant mothers’ breathing becomes heavy and they are out of breath even with a little exercise. This is caused by the uterus rising toward the lungs and compressing the lungs. The pregnant mother\’s weight at this time has increased by 5 to 6 grams compared with before pregnancy. The lower body is prone to fatigue, the waist and back will feel pain, and foot edema or calf cramps may occur at night.
