menstrual cycle

Amenorrhoea is the failure to menstruate and it is usually described as being primary or secondary.

The Menstrual Cycle is a series of events that occurs over a period of time that prepares the lining of the uterus (womb) for pregnancy through the implanting of a fertilised egg. If a pregnancy doesn’t occur, then the lining of the womb that has been built up is shed through menstruation (period).
