The fetal movement is not felt in the fourth month of pregnancy is also a normal performance, as long as the ultrasound examination fetal development is normal, there is no need to worry too much, generally in the 4.5-5 months of fetal activity will be more obvious, especially the first maternal abdominal wall tension, for fetal movement is not particularly sensitive, can not correctly judge the phenomenon of fetal movement, so will not feel the obvious fetal movement. If you are a woman in labor, your abdominal wall is more relaxed and you can make accurate judgments about fetal movement, so you will feel the fetal movement a little earlier. The number of fetal movements and the frequency of fetal movements during pregnancy are also related to external factors, if you are nervous or overly excited, too much activity will also lead to too frequent fetal movements or more obvious fetal movements.
