Is it normal to have menstruation again after six months of menopause during perimenopause?

It is normal for menstruation to return after six months of menopausal amenorrhea. During menopause, hormonal imbalances and gradual ovarian decline may lead to menstrual irregularities. If the menstrual flow is light and gradually decreasing, and the cycle hasn't significantly shortened, observation may be sufficient. However, during this period, some women may experience increased menstrual flow and prolonged periods. If menstruation lasts longer than seven days, an ultrasound at the hospital is recommended. If bleeding occurs more frequently or in larger amounts than usual, prompt treatment is necessary to prevent excessive bleeding and resulting anemia.
