If the pregnancy is terminated in the third month of pregnancy, it may cause the following hazards clinically: 1. Because the days of pregnancy are longer, doing abortion may cause excessive bleeding and cause hemorrhagic shock. 2. The amniotic fluid has formed in the third month of pregnancy, which may cause amniotic fluid embolism, causing coagulation dysfunction and even threatening the life safety of the pregnant woman. 3. Because doing abortion is likely to cause pathogenic bacteria The abortion may cause acute inflammation of the pelvic cavity and symptoms such as high fever and chills, and anti-inflammatory treatment should be given in time. 4. It may cause damage to the cervix because abortion cannot be performed in the third month of pregnancy, and the drug can only be inserted into the posterior vaginal fornix, and then cause contractions, which may cause laceration of the cervix due to strong contractions. These are the dangers of terminating a pregnancy in the 3rd month of pregnancy.
