In the eighth month of pregnancy, if there is a slight bleeding phenomenon, this is considered the possibility of preterm labor. If the bleeding is not heavy and there is no pain in the stomach, take care to rest in bed for the time being and observe. If there is an increase in the amount of bleeding, or if there is pain in the stomach, or if the pain is accompanied by a hardening of the stomach, you should go to the hospital promptly for birth control. The pain and hardness of the stomach are signs of uterine contractions and preterm labor. If the fetal heartbeat is not normal or the fetal movement is not normal, it is considered to be a sign of intrauterine ischemia and lack of oxygen. If excessive vaginal bleeding occurs during this period, it will easily lead to the occurrence of intrauterine infection, and timely antibiotics are also needed to prevent infection.
