Repeated bleeding during pregnancy is an abnormal condition that should be examined promptly to determine the cause and then treated symptomatically. Avoid repeated and prolonged bleeding, which can affect the health and growth of the fetus and in serious cases may cause miscarriage or preterm delivery. If you have recurrent bleeding in early pregnancy, you should first check the progesterone in time. If the progesterone value is low, you should take progesterone orally or inject progesterone intramuscularly for fetal preservation treatment in time. If you have recurrent bleeding in the middle of pregnancy, you should also pay attention to see if there is any belly pain, if there is no belly pain, consider placenta praevia or marginal placenta praevia, this situation also needs to do ultrasound examination to determine.
