It is possible for women to have two menstrual cycles per month according to the U.S. Department of Health and Human Services. This can occur either if she has it at the very beginning of the month and then again at the very end in a typical 28 day cycle, or it can happen more frequently as a sign of reproductive issues.
Women can have two or more menstrual cycles per month. This is as a result of having a period at the very beginning of one month, and then again at the end of the month, in a normal 28 day cycle. However, there are circumstances in which there are reproductive problems that can cause a woman to have two or more periods in a month. This is called metrorrhagia, or frequent menstrual periods, and ovarian cysts or other reproductive disorders can cause this problem, according to Core Physicians. When dealing with multiple menstrual cycles each month that are more frequent than a normal 28 day cycle, visiting a gynecologist for a check-up is recommended.
