Generally there is no such thing as signs of low amniotic fluid in pregnant women. If a woman has low amniotic fluid during pregnancy, she may experience pain during fetal movement, abnormal number of fetal movements, and small pregnant belly. 1. Fetal movement pain: due to the small amount of amniotic fluid, it will limit the range of fetal activities, so the symptoms of abdominal pain may occur when the fetus moves. 2. Abnormal fetal movements: pregnant women may feel that the number of fetal movements decreases, or the number of fetal movements is too frequent, because when the amniotic fluid volume is low, the fetus will lack oxygen, resulting in an abnormal number of fetal movements. 3. Small belly of pregnant women: Since the abdominal circumference and fundal height are related to the size of the fetus and the amount of amniotic fluid, if the amount of amniotic fluid is low, the abdominal circumference and fundal height of pregnant women will be smaller than the normal pregnancy months. If the above symptoms occur, it is recommended to consult a doctor in time, follow the doctor’s instructions to carry out relevant examinations, with the help of the doctor to clarify the cause of the disease, targeted treatment or treatment.
