It is important to pay attention to bleeding that occurs more than ten days after menstruation, as there are many potential causes for this situation, such as functional uterine bleeding, contact bleeding, molar pregnancy, use of emergency contraceptives, vaginal bleeding in postmenopausal women, bleeding during ovulation, etc. Here are some details:

1. Functional Uterine Bleeding

This is a common clinical condition manifesting as irregular menstrual cycles, excessive menstrual flow, prolonged menstruation, or irregular bleeding. The principle of treatment is to rapidly stop the bleeding, adjust and establish a normal menstrual cycle, and prevent recurrence.

2. Contact Bleeding

This type of bleeding often occurs after sexual intercourse and is often associated with gynecological diseases such as vaginitis, cervical erosion, cervical polyps, early cervical cancer, and submucosal fibroids.

3. Molar Pregnancy

Women who have previously suffered from molar pregnancy and have recurrent episodes after treatment may also experience bleeding after menstruation. This situation may be an early symptom of malignant molar pregnancy, and immediate medical attention is required.

4. Use of Emergency Contraceptives

The effect of emergency contraceptives on menstruation is mainly manifested in changes in menstrual cycles, which may be earlier or delayed. Frequent use may lead to menstrual disorders and excessive menstrual bleeding.

5. Vaginal Bleeding in Postmenopausal Women

Due to vaginal dryness after menopause, vaginal mechanical injury and bleeding can easily occur during sexual activity if no lubricant is used. With increasing age, the risk of cervical cancer and uterine cancer also increases, so regular checks are necessary.

6. Bleeding During Ovulation

The amount of bleeding in this situation is usually small, with some people experiencing only a small amount of brownish discharge. It usually lasts for half a day or 2-3 days, and no more than 7 days. It may be accompanied by mild ovulation pain and lumbar soreness. If the symptoms are mild, no treatment is required, but if the symptoms are obvious, medical attention should be sought promptly.
