During pregnancy, women should not use their hands to press their bellies. External pressure on the abdomen during pregnancy can adversely affect the fetus and may cause miscarriage or premature delivery. Some pregnant women may think that the doctor’s force will affect the fetus during the test, but in fact, the doctor’s force during the test is regular, and the amniotic fluid is already formed when the NT test is done, and the fetus is floating in the amniotic fluid in the uterus. The amniotic fluid can effectively cushion the external force on the fetus, and has a certain radiation protection effect, which will not affect the fetus. If you experience abdominal discomfort during pregnancy, you should seek medical treatment in a timely manner, and you can undergo ultrasound examination and treatment under the guidance of a doctor. Avoid strenuous exercise during pregnancy and try not to press on the abdomen to avoid affecting the healthy development of the fetus. It is also necessary to strengthen the diet during pregnancy, which should match meat and vegetables with balanced nutrition, which can ensure the healthy development of the fetus. It can also prevent anemia and malnutrition during pregnancy, but reduce the consumption of stimulating, cold, greasy food.
