Early ectopic pregnancy usually does not cause fever, but only early pregnancy reactions such as amenorrhea, abdominal pain, nausea and vomiting. As the gestational sac increases, the site of ectopic pregnancy cannot adapt to embryonic development, which can easily cause local rupture leading to bleeding and fever symptoms, because the blood is easy to show fever symptoms during the absorption process. In addition, excessive bleeding can cause intra-abdominal infection and fever. The fever during blood absorption is low and will not exceed 38°C. If there is infection in the abdominal cavity, it is easy to cause high fever if not controlled in time. You can go to the hospital for routine blood tests and consider abdominal infection caused by increased white blood cells. It needs to be treated with antibiotics such as ceftriaxone sodium.
