The body temperature of ectopic pregnancy will also rise. The progesterone in the body will rise during ectopic pregnancy, which will stimulate the central nervous system and cause an increase in body temperature. However, if the temperature rises too high, it may be caused by bacterial or viral infection. In addition, when the site of ectopic pregnancy ruptures, it is easy to cause an increase in body temperature. However, the change in temperature alone cannot determine ectopic pregnancy and intrauterine pregnancy, so it is necessary to have blood tests for HCG and ultrasound examination and posterior fornix aspiration examination. If this fails, surgery should be performed in time.
