Frequent fetal movement in more than 5 months of pregnancy is considered to be a sign of intrauterine ischemia and hypoxia of the fetus. Because under normal circumstances, the number of fetal movements should be between 4-6 times per hour, if it is more than 6 times, it is a phenomenon of frequent fetal movements. During uterine contractions, the number of fetal movements will increase, but the symptoms will improve after rest. If fetal movements are too frequent, an ultrasound should be performed. If it is determined that the fetus has intrauterine ischemia and hypoxia, the pregnant woman should be given oxygen to improve the symptoms. During this period, if there is frequent fetal movement, it will trigger contractions, and in serious cases, it will lead to miscarriage. Therefore, strict attention should be paid to observation during this period. If stomach pain occurs, it should be timely treated with birth control drugs, such as Ritodrine, to avoid excessive uterine contractions leading to miscarriage.
