Perimenopause basics
Perimenopause is the stretch of years when cycles, hormones, and symptoms often become less predictable, before menopause is reached. Researchers usually call this the menopausal transition. “Menopause” itself is a point in time: twelve months without a period after the final menstrual period.
Timing varies widely. Many people spend about four years in the transition, and the typical age at menopause is around 51. Those are population averages, not a clock for any one person.
Tracking what you notice — sleep, bleeding, hot flashes, mood, energy — can make later conversations with a clinician more concrete. A log describes your pattern. It does not assign a stage, predict an end date, or replace a clinical assessment.
If something feels urgent, new, or unlike your usual pattern, that is a reason to talk with a qualified clinician rather than wait for an app to interpret it.
What this article cannot tell you

Questions worth taking to a clinician
- Do my bleeding changes fit a menopausal transition pattern, or should we look for another cause?
- Which symptoms are worth tracking before my next visit?
