Four menstrual periods in two months?

It is not common to have four menstrual periods in two months. A typical menstrual cycle lasts between 21 and 35 days, with an average of 28 days. Having a period more frequently than every 21 days is considered abnormal and may be a sign of an underlying medical condition. It's important to see a healthcare provider if you experience four menstrual periods in two months to rule out any potential health problems and receive appropriate treatment if necessary.
