If the usual menstrual cycle is normal and the menstrual period is also normal. The case of leukorrhea immediately after the menstrual period has just stopped, consider that it is not ovulation, because ovulation is about 14 days before the next menstrual period. It is usually considered to be caused by vaginal inflammation, or incomplete treatment, which is prone to recur after the menstrual period is cleared. It is recommended to go to the hospital for further examination of the leukorrhea routine, to clarify the type of inflammation, and then give symptomatic treatment. The increase in leukorrhea on the first day after menstruation may also be caused by hormonal changes in the body, which can be observed or tested with ovulation test paper, which, if it shows strong positivity, indicates that it is the period of ovulation.
