Hi, Having a menstrual cycle every two weeks can be a sign of various underlying conditions, and it s important to see a healthcare provider for a proper diagnosis and treatment. Here are some possible causes of frequent periods: * Hormonal Imbalance: Hormonal imbalance is a common cause of irregular menstrual cycles. Fluctuations in estrogen and progesterone levels can cause the uterine lining to shed more frequently. * Polyps or Fibroids: Polyps and fibroids are growths that can develop in the uterus and can cause bleeding between periods or more frequent periods. * Endometriosis: Endometriosis is a condition where tissue similar to the lining of the uterus grows outside of the uterus. This can cause pain and heavy bleeding during periods, as well as bleeding between periods. * Thyroid Issues: Thyroid imbalances can disrupt the menstrual cycle and cause irregular bleeding. * Pelvic Inflammatory Disease (PID): PID is a bacterial infection of the reproductive organs that can cause abdominal pain and irregular bleeding. * Cervical or Uterine Cancer: In rare cases, irregular bleeding or frequent periods can be a sign of cervical or uterine cancer. It s important to see a healthcare provider for an evaluation if you are experiencing frequent periods, as well as severe pain, migraines, and nausea. A pelvic exam, blood tests, and imaging tests may be recommended to determine the cause of your symptoms. Treatment options may include medications, such as hormonal contraceptives or pain relievers, or in some cases, surgery. Take care. Hope I have answered your question.
