After 28 weeks of pregnancy, the fetus in the belly from an embryo becomes a medical sense of “perinatal”, that is, ethically really become a person, and at this time, the most important homework for pregnant mothers will begin, that is – counting fetal movements. The fetal movement is the easiest and most intuitive means to monitor the status of the fetus, when the baby has intrauterine hypoxia or abnormal, fetal movement is often the first signal to the outside world, pay attention to these signals and timely treatment, often can reduce the stillbirth rate of 70%. So it is very necessary to develop a good habit of counting fetal movements in late pregnancy. So, how to count the fetal movements? First of all, the fetus does not move every moment, it has its own sleep cycle, which is often intermittent and lasts about 20-40 minutes each time. In addition, as the fetus grows later in pregnancy, the fetal movements will become more regular. Once you understand this, you can start looking for your baby’s fetal movement pattern. The pattern of fetal movement varies from baby to baby, but most babies are active in the morning, after eating (especially after eating sweets), after the mother takes a bath or exercises, or after dinner until nighttime. When counting fetal movements, mothers can choose a quiet and comfortable sitting position, or left side lying position so as to keep the fetus in an active position, and choose a more active fetal period in the morning, midday and evening every day, one hour each, if the fetal movements >3 times per hour, that is normal. If the total number of fetal movements in these three time periods is multiplied by 4, the number of fetal movements in 12 hours will be normal, >30 times, <10 times indicates fetal hypoxia, or fetal movements are significantly less than 50% of the average number of fetal movements, which also requires medical attention. This method of counting fetal movements is also the most common monitoring method of the existing APPs on the market, and it is quite convenient to use. Another way to count fetal movements is the method recommended by the American College of Obstetricians and Gynecologists (ACOG). That is, the time it takes to monitor 10 fetal movements during the period of regular daily activity of the baby, <2 hours is considered normal, and the average time of 10 consecutive fetal movements for most mothers is 20.9 minutes. You can keep a table counting the time of 10 fetal movements per day to observe the regularity and changes of fetal movements, which can also be easily given to your obstetrician as a basis for monitoring the fetal condition. Of course, the change of fetal movement is sometimes closely related to the state of the mother. If your life is not regular, if you are excited, if you are overworked, the fetal movement may change accordingly. At this time, you need to adjust your own state, analyze the subtle difference between the day and the usual, and closely observe the change of fetal movement.
