When a woman is 22 weeks pregnant, the fetus’ genitalia have grown and the parenchymal organs are basically formed, and also the fetus’ mouth, eyes and hands can be seen on the ultrasound with obvious movements At this time, the baby’s weight is about 350 grams, and the length of the body is about 19 cm, and also the baby’s eyebrows and eyelids can be seen through the ultrasound, and delicate nails are growing on the ten little fingers, as this time Since the gestational week is not particularly large at this time, the subcutaneous fat of the fetus has not yet been produced, and the baby is seen to be like a little old man at this time. At the same time, the fetus has a wide range of movement in the uterine cavity, because at this time the baby is relatively small, and the amount of amniotic fluid is relatively large, so when the fetus is moving, it can generally have obvious fetal movement. Most of the pregnant women will have a significant weight gain at this time, but the details of the weight gain will vary from person to person. Some women may gain around five kilograms at this time, while others may gain up to ten kilograms, so an OGTT test is required at around 28 weeks of pregnancy to check for gestational diabetes. And at 22 weeks of pregnancy, you can usually consider a 4D ultrasound to perform a major abnormality test.
