In the late stages of pregnancy, if there is a small amount of vaginal bleeding and a hard and tight stomach, this indicates that the uterus is contracting and signs of preterm labor are occurring. If you have not yet reached the due date, you should go to the hospital in time to keep the baby. If you have reached the expected date of delivery, it is a sign that you are going to give birth. If the fetal heartbeat is normal, there is no need for special treatment and you should wait for regular contractions and go to the hospital for delivery later. If there is abnormal fetal movement or abnormal fetal heartbeat during this period, you should go to the hospital for oxygen as soon as possible and in time. In severe cases, it is also necessary to terminate the pregnancy and do a cesarean section in time to avoid intrauterine distress of the fetus.
