menstrual cycle
Let an agent explain the menstrual cycle and its phases in general terms from health sources, relay normal variation, tracking and common problems, and route personal health questions to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the menstrual cycle and its phases in general terms from health sources, relay normal variation, tracking and common problems, and route personal health questions to clinicians.
The recurring series of hormonal and physical changes in the female reproductive system that prepares the body for possible pregnancy, lasting about 28 days on average with a normal range of about 21 to 35, comprising the follicular phase, ovulation and the luteal phase, and ending in menstruation if no pregnancy occurs, with anovulatory cycles in which no egg is released; the cycle is regulated by hormones from the hypothalamus, pituitary and ovaries and is affected by health, age and contraception.
What it is for: Not applicable; a physiological process.
It can be explain phases and hormones; relay normal variation; describe tracking and common problems; route personal questions.
Distinguishing features

What it looks like
Not a visible object; a cycle of physiological changes.
Physical character
average length: about 28 days - normal range about 21-35
menstruation length: about 3-7 days
How it is recognised
Recurring reproductive cycle
Follicular phase, ovulation, luteal phase, menstruation, anovulatory cycles
The estrous cycle is the equivalent in many other mammals; pregnancy interrupts the cycle
