Quick Answer. A typical menstrual cycle is between 24 and 34 days long. However, some women have an even shorter cycle which can cause two periods in one month, according to the New York Times. While a short menstrual cycle can be completely normal for an individual woman, bleeding twice in one month can also be a signal of an underlying disorder; visiting the doctor to discuss any abnormal bleeding is advised.
Reasons for Having a Period Every Two Weeks. The menstrual cycle occurs in all females from the onset to puberty (average age 11 or 12 years) to the menopause in middle age (average age between 45-55). The lining of the uterus is shed via vaginal bleeding when a girl or woman has not conceived a pregnancy.
