Abnormal leukorrhea does not usually cause delayed menstruation. Abnormal leukorrhea mostly indicates gynecological inflammation, which is common in mycosis vaginalis, trichomoniasis, senile atrophic vaginitis, and bacterial vaginitis. The presence of gynecological inflammation does not necessarily cause changes in menstruation, but only itching of the vulva, odor of the discharge, pain in the vulva and vagina, and changes in the nature of the discharge. Patients with mycosis fungoides may have typical tofu-like or curd-like discharge, in which case they need to be treated with antifungal medication, but it will not affect the menstrual flow, which will continue to occur at any time.
