A pile of leukorrhea at its thickest does not indicate ovulation. If such leukorrhea occurs during ovulation and is not accompanied by abnormal symptoms, it only indicates the possibility of ovulation in the patient. The higher estrogen levels and increased levels of luteinizing hormone during ovulation can change the nature of the patient’s vaginal discharge, making the leukorrhea thicker, jelly-like or stretched and transparent. However, in some cases, the follicles grow well after the change in hormone levels, but are not completely expelled. Therefore, it is not possible to determine whether ovulation is over or not by the nature of the leukorrhea alone. Clinically, the ovulation can be more accurately determined by ultrasound examination. In addition, if the leukorrhea is heavy with itching and peculiar odor, the patient is considered to have bacterial vaginitis and needs to use medication under the guidance of a doctor. Therefore, if the patient is worried about ovulation, it is recommended to go to the hospital for follicle monitoring in order to know more accurately when ovulation will occur.
