Under normal circumstances, the normal fetal movement in 20 weeks of pregnancy is 3-5 times/hour, and can reach 30-40 times in 12 hours. However, the fetus is still small and not very strong during this period, and the feeling of fetal movement is also if any, most pregnant women can only feel slight fetal movement during the 20th week of pregnancy. If you can’t feel the fetal movement at this time, there is no need to worry, because everyone’s body reaction condition will be different, the common situation are the following: 1, personal sensitivity: more sensitive pregnant women will be more sensitive to fetal movement, the fetus can feel every fetal movement, if the pregnant woman itself is less sensitive, the fetus will not be very obvious; 2, quiet temperament: the fetus senses the pregnant woman’s emotions, if the pregnant woman herself If the pregnant woman herself is quiet in nature, she will be more careful and cautious in pregnancy, it is difficult to have big activities, the fetal activity will also be lower, so the fetal movement will be less. It is recommended that pregnant women should do proper exercise during pregnancy so that the fetus will be lively; 3, pregnant women have thicker skin fat: pregnant women will eat more food during pregnancy, resulting in more body fat and thicker skin, so pregnant women will feel that the fetal movement is not obvious; 4, amniotic fluid buffer: the fetus is protected by amniotic fluid in the womb, which can have a buffering effect, and when the fetus is moving, some movements will be relieved by the amniotic fluid, so The amplitude may become smaller. During pregnancy, you should have regular maternity checkups, pay attention to doing more exercise in general, avoid hypertension and hyperglycemia in pregnancy as well as obesity during pregnancy. It is recommended to eat less and more meals, eat more milk, tofu, vegetables, lean meat and other foods rich in calcium, potassium and magnesium, and avoid hot foods such as chocolate, chili and cinnamon. As the fetus keeps getting bigger, you can basically feel the obvious fetal movement after 22 weeks of pregnancy.
