The fetal movement has a normal range, not more and not less is best, there is a certain pattern, the daily fetal movement basically does not change too much, so pregnant mothers should learn to count the fetal movement since, pay attention to observe. Usually after 28 weeks of pregnancy, you need to count fetal movements every day and observe the frequency of fetal movements, generally a continuous activity of fetal limbs or body is called a fetal movement. It is recommended to count the fetal movements at a fixed time every morning, noon and night, each time for 1 hour, adding up the number of 3 fetal movements and multiplying it by 4 to get 12 hours of fetal movements. Normal fetal movement is not less than 3-5 times in an hour, and the total number of fetal movements in 12 hours is more than 30-40 times. If the number of fetal movements is less than 3 times in 1 hour and less than 20 times in 12 hours, or if the number of fetal movements is too frequent compared to usual, and the number of fetal movements is more than 10 times in 1 hour, you should be alert to the possibility of fetal hypoxia in the uterine cavity and go to the hospital for ultrasound and electronic fetal heart monitoring to clarify the specific situation in the uterus. In addition to counting fetal movements during pregnancy, you can also listen to the fetal heartbeat, measure the uterine height and abdominal circumference or measure the weight of the pregnant mother once a week to observe the intrauterine development of the fetus.
