Wavy fetal movement means that the fetus is performing different kinds of physical activities inside the uterine cavity, such as rolling over, kicking the legs, shaking the arms, etc. The strength of different activities varies, thus forming wavy fetal movements. Wavy fetal movement refers to the process of fetal movement from weak to strong, and then from strong to weak. If the movements are of this shape, it means that the fetus is performing different kinds of physical activities inside the uterine cavity, such as kicking its legs, shaking its arms, and rolling over, which is a relatively normal phenomenon. However, if the changes in fetal movement are too frequent, it means that there may be intrauterine hypoxia, which requires further examination in the hospital. Therefore, pregnant women should go to the hospital regularly for medical checkups and pay attention to their diets, supplement their nutrition in time, and eat more vegetables and fruits, so as to promote the development of the fetus.
