A fever during ovulation is generally an abnormal sign. Although there is an increase in body temperature during ovulation, it does not reach the level of a fever. A fever during ovulation may be a coincidence, that is, a fever caused by illness during this period of ovulation. For example, respiratory infections such as colds, bronchitis, bronchiectasis and even pneumonia can cause fever during ovulation. In addition, gastrointestinal infections, urinary tract infections and reproductive system infections may also cause fever. Common diseases include acute gastroenteritis, acute pyelonephritis, urethritis, pelvic inflammatory disease, etc. If fever occurs during ovulation, it is usually not a normal manifestation. Patients are advised to drink more water and take rest. If the fever is high, physical cooling and oral antipyretic drugs can be taken. If the temperature continues to rise and cannot be relieved by the above measures, the patient should seek medical attention as soon as possible for blood tests, imaging examinations, etc. to clarify the specific cause of the fever and actively target the cause for treatment. If there is a plan to get pregnant, it is recommended to avoid getting pregnant in the same month and re-plan the time of pregnancy after the specific cause is clarified.
