The amplitude of fetal movement in the 36th week of pregnancy will decrease appropriately, but the frequency of fetal movement will not change significantly, when the fetus suddenly does not move much is not normal.
Fetal movement usually appears around 20 weeks of pregnancy, and reaches its peak around 32-34 weeks of pregnancy, while the 36th week of pregnancy the fetus grows faster, and the space available for intrauterine activity decreases, the amplitude of fetal movement will be appropriately reduced. When the fetus does not move much is not normal, it is recommended that timely fetal heart monitoring to avoid intrauterine distress.
Pregnant women can choose to count the fetal movement in a quiet environment, take the left side of the lying position, take the morning, midday and evening each hour counting, continuous fetal movement is recorded as a time, not less than 3-5 times per hour counting.
The number of fetal movements in 3 hours is added up and multiplied by 4 is the number of movements in 12 hours. When the number of movements in 12 hours is less than 10 or less than 50% of the average number of movements, the fetus is considered hypoxic and requires prompt medical attention.
Therefore, if your baby is not moving much in the 36th week of pregnancy, it is recommended that you seek prompt medical attention in order to identify the specific cause.
