Premenopause
Premenopause is the reproductive life stage preceding perimenopause, spanning the years of regular ovulatory cycling from adolescence through the late thirties or early forties. Hormonal patterns during premenopause are comparatively stable: estradiol and progesterone follow predictable monthly rhythms, FSH remains within normal range, and AMH sits at or near its lifetime peak. This is the window of highest natural fertility for most women.
Cycle charting during premenopause builds a baseline record that becomes diagnostically valuable later. Changes in mucus quality, cycle length, post-peak phase duration, or premenstrual spotting appear in the chart years before they produce symptoms severe enough to prompt a clinical visit. For RRM clinicians, a woman's premenopausal charting history is a longitudinal dataset, not just a contraceptive tool.1
Premenopause ends when the cycle begins to shift into the variable, hormonally volatile pattern that characterizes Perimenopause. The transition is biological, not calendar-defined.
