If bleeding occurs during the course of taking Ursine, it is usually normal if it is not caused by a missed dose. If the bleeding is not heavy, it can be temporarily observed and not treated. If the bleeding is heavy, it may be withdrawal bleeding or endometrial polyp or inflammation of the endometrium. Therefore, if the bleeding is prolonged or heavy, it is recommended to stop taking Eusebio and see a doctor for an ultrasound examination to understand the condition of the uterine adnexa and endometrium to exclude organic lesions. If there is no abnormality, you can continue to take Eusebio in the second cycle, both for adjusting the menstrual cycle and for effective contraception. However, it is important to avoid missing doses during the course of Eusebio, as this may cause breakthrough bleeding or contraceptive failure.
