If fetal movements are frequent and regular and there are no other uncomfortable symptoms, there is usually no problem. If the fetal movements are suddenly frequent and irregular, it may be due to lack of oxygen in the fetus or collision of the pregnant woman. Some pregnant women can hear the sound of mom and dad’s voice in late pregnancy after eating or taking a bath, which will also make the fetus move frequently. These are normal situations, don’t worry too much. Frequent fetal movements in early pregnancy may also be the early stages of hypoxia, where the number of fetal movements will increase and be irregular. If bumping occurs, the fetus will also experience frequent fetal movements, which may also cause early placental abruption and jeopardize the health of the fetus. It is recommended that pregnant women should start from the 28th week of pregnancy to measure their own fetal movement, counting 1 hour each day in the morning, midday and evening, and multiplying the number of fetal movements in 3 hours by 4, that is, the number of fetal movements in 12 hours, generally 30-40 times is normal. If abnormal fetal movement occurs, it is recommended to consult a doctor in a timely manner, follow the doctor’s instructions for relevant examinations, with the help of the doctor to clarify the cause of the disease, targeted treatment or treatment.
