I am 41 years old and have two menstrual cycles per month. How can I regulate it?

Patient's question:

6 months, one period in January twice

Doctor's answer:

Two menstrual periods in a month may likely be caused by other gynecological conditions, such as ovulatory bleeding, functional uterine bleeding, uterine fibroids, endometriosis, or contact bleeding. These factors can all lead to irregular periods in women. It is recommended to undergo a thorough examination for a clearer diagnosis.
