No fetal movement at 16 weeks of pregnancy is generally a normal performance, most pregnant women will appear around 18 to 20 weeks of pregnancy, as long as the results of the obstetric examination are normal.
At 16 weeks of pregnancy, the development of the fetus is not very large, although it may be appropriate activities in the uterine cavity of the pregnant woman, but the amplitude of the activities is relatively small, the movement is relatively slight, it is difficult to check the fetal movement through the abdominal wall of the pregnant woman. Therefore, if there is no fetal movement at 16 weeks of pregnancy, most of them are normal manifestations, and if the fetus grows and develops well, no special treatment is usually needed.
In about 18 to 20 weeks of pregnancy, the fetus in the uterine cavity gradually grows, the amplitude of activity increased significantly, the movement is more obvious, may cause obvious stimulation of the abdominal wall, you will feel the fetal movement.
