In the late stages of pregnancy, when the stomach appears like menstrual cramps, this is considered to be an aura of labor. During this period, there will be contractions, resulting in pain in the stomach and accompanied by symptoms of hardness. If this happens when you have reached the due date, it is an aura of labor. If the fetal heartbeat is within the normal range and the amniotic fluid is moderate, you can wait for delivery. If the fetal heartbeat is abnormal, the fetal movement is reduced, or the amniotic fluid is cloudy, the pregnancy should be terminated in time.
