Functional uterine bleeding, clinically divided into ovulatory and anovulatory functional uterine bleeding, presents differently depending on the type. Typically, the clinical manifestation of anovulatory functional uterine bleeding includes prolonged menstrual dripping or heavy vaginal bleeding. In such cases, it is recommended that patients seek immediate medical attention at a local hospital for a clear diagnosis and timely treatment. Ovulatory uterine bleeding is often characterized by changes in the menstrual cycle; some women may experience a shortened cycle, while others may have an extended menstrual cycle.
