Bleeding after periods can be caused by various factors, including hormonal changes, injury, infections, and certain health conditions. Here are some of the possible causes of bleeding after periods:

• Hormonal changes: Hormonal imbalances can cause bleeding between periods, especially during the first few months of starting hormonal contraception.

• Injury: Injury to the vagina or cervix, such as from having penetrative sex, can cause bleeding between periods.

• Infections: Infections in the reproductive organs can cause inflammation and bleeding, leading to bleeding between periods.

• Health conditions: Certain health conditions, such as endometriosis, polyps in the uterus or cervix, fibroids, and cancer, can cause bleeding after periods.

If you experience bleeding after periods, it is important to see a doctor for testing, diagnosis, and treatment options. Diagnostic tests can help your doctor find the cause of the bleeding, which may include blood tests, cultures, biopsies, and ultrasounds. Treatment will vary based on what’s causing your abnormal vaginal bleeding, and may include medication, surgery, or other interventions.
