Normally, women do not have a period after menopause, but some women may have an occasional period within six months after menopause because they are in the perimenopausal phase. This is because menopause is not a sudden absence of menstruation, but a process is required. From the time a woman begins to experience pre-menopausal symptoms to within 12 months after menopause, the medical term is perimenopause. Due to the gradual decline of ovarian function, from the beginning of perimenopause, women will experience menstrual disorders and other symptoms, and the intermenstrual interval will gradually increase until menopause. It is possible to have an occasional menstrual period within six months after menopause, which is usually functional uterine bleeding and can be observed if there are no physical symptoms. However, for menopausal women, i.e. abnormal vaginal bleeding more than 1 year after menopause, we must pay great attention to it and do not exclude endometrial cancer, cervical cancer and other diseases, so we need to go to the hospital for gynecological examination and ultrasound examination in time to clarify whether there are lesions in the uterus.
