When women experience dysfunctional uterine bleeding, the clinical symptoms are varied. For example, some women still have a relatively regular menstrual cycle, occurring monthly, but exhibit bleeding between periods, such as the most common ovulatory bleeding. Other women experience vaginal bleeding before or after their period, such as when there is an abnormality in the function of the corpus luteum, leading to brown vaginal discharge clearly related to the menstrual cycle. Some women have irregular menstrual cycles, with no predictability of when menstruation will occur, characterized by intermittent spotting or irregular vaginal bleeding. If such conditions persist, they can lead to anemia from blood loss in women, manifesting as dizziness, fatigue, sleepiness, and loss of appetite.
