Under normal circumstances, 5 months of pregnancy should be able to feel fetal movement, if you can not feel fetal movement, it may be related to abnormal fetal development, maternal obesity, low intensity of fetal activity and other factors. 1, abnormal fetal development: fetal development is relatively slow or due to intrauterine ischemia and hypoxia, resulting in the death of the embryo or stop development, may not feel fetal movement, at this time to the hospital for ultrasound examination, to Observe the development of the fetus and terminate the pregnancy if necessary; 2, maternal obesity: if the pregnant woman is obese and has more abdominal fat, it will lead to insensitive perception of fetal movement, and in the fifth month of pregnancy, the fetus is relatively small, the strength and amplitude of the movement is also relatively small, so it will not feel the fetal movement, ultrasound examination can be conducted to clarify the development of the fetus in the uterus; 3, low intensity of fetal activity: because the activity of each fetus The intensity of each fetus is different, some fetus activity intensity is relatively low, in this case may also not feel the clear fetal movement, can carry out ultrasound examination to clarify the fetal intrauterine state. Therefore, the inability to feel fetal movement in the 5th month of pregnancy is mostly caused by physiological factors, generally as the pregnancy week increases the fetus will gradually increase in size, and the fetal movement will be felt gradually. If you can’t feel the fetal movement all the time, you can also go to the hospital to improve the examination to clarify whether there is any abnormal situation.
