Menstruation every month should defer how to return a responsibility

Menstruation will be delayed every month, it may be because your menstrual cycle is relatively long. Women's menstrual cramps are regular, the interval between two menstrual periods is about 28 to 35 days. If your menstrual cycle is relatively long, each month's menstruation will be delayed. But the delay time is generally not more than a week. If your menstruation is delayed for more than a week, it may be caused by insufficient blood and endocrine disorders.
