Possible causes of ovulatory flow are: 1. normal: during ovulation, women’s vaginal mucus becomes thin, with more discharge and dilute watery; 2. abnormal: increased vaginal discharge due to inflammation of the reproductive system. The specific diagnosis also needs to be combined with the patient’s gynecological examination as well as routine white belt examination and past disease history for comprehensive judgment. If there are no other abnormal clinical manifestations of ovulatory flow, pay attention to rest and avoid staying up late; avoid cold food and do not be overly anxious; go to a regular hospital obstetrics and gynecology department for formal examination. If ovulatory flow is accompanied by local discomfort in the vulva, it is recommended to go to the obstetrics and gynecology department of a regular hospital for further consultation and treatment.
