<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, I have been having some strange symptoms lately. My menstrual cycle has stopped completely and I have been experiencing vaginal itching and pelvic pain. Also, sometimes I get unpredictable periods. What could be the reason for this?  <response>: It sounds like you might be going through menopause. Menopause is a natural biological process that marks the end of menstrual cycles. The absence of menstruation, vaginal itching, pelvic pain, and unpredictable menstruation are all common symptoms of menopause. I would suggest some lifestyle changes or hormone therapy to alleviate your symptoms.
