In the 8th month of pregnancy, it is normal for the fetal movement to decrease slightly, but if it decreases significantly, it is necessary to find the specific cause after examination. In the 8th month of pregnancy, as the fetus grows, the space for movement in the uterus will gradually decrease and the fetus will have difficulty moving around, so the fetal movement may decrease slightly. If the fetal movement is counted during the baby’s sleep time, the fetal movement will also be reduced, then you can measure it again at intervals, and if it can return to normal, it is also normal. However, if the fetal movement decreases significantly, <10 times in 12 hours, you need to be alerted to the risk of fetal hypoxia, and then you need to seek medical attention as soon as possible to determine through a more professional examination in the hospital. If there is a problem, further treatment such as oxygenation may be required. Counting fetal movements is a simple means for pregnant women to monitor the condition of their fetus. In addition to the fetus itself, it can also be affected by the pregnant woman's food, activity and sleep, so every number of fetal movements may be different, and pregnant women do not need to be overly anxious.
