Phases of the menstrual cycle. The menstruation cycle refers to the cycles in which a womanâs uterus grows and sheds a lining (the endometrium) which could support the development of a fertilised egg. It typically occurs in 28 day cycles, so a woman generally gets her period every 28 days.
Shedding of the functional endometrial lining is responsible for menstrual bleeding (known colloquially as a period in humans, with a cycle of approximately 28 days, +/-7 days of flow and +/-21 days of progression) throughout the fertile years of a female and for some time beyond.
