What happens at each stage
Three stages, not one event: perimenopause, menopause, and postmenopause. Most of what gets called "menopause symptoms" in everyday conversation actually happens during perimenopause, the stage before the menopause point itself.
Perimenopause
The transition leading up to the final period. Cycles become irregular — more or less frequent, heavier or lighter — and this is when most people first notice symptoms: hot flashes, sleep disruption, mood changes, and others. There's no fixed start age or fixed duration; it varies widely between people.
Menopause
A single point, not a stage — defined as 12 months without a period, identified only in hindsight. Nothing distinguishes the day itself; it's simply the day the 12-month count is satisfied. Symptoms don't reset or resolve on this date — it's a calendar marker, not a physiological switch.
Postmenopause
Everything after the menopause point. Some symptoms that started in perimenopause ease off over time; others persist, and there's no fixed timeline for either. Two things are specifically worth knowing about this stage:
- Postmenopausal bleeding — any bleeding after the 12-month mark — is a defined reason to seek assessment, distinct from the ordinary irregular bleeding of perimenopause.
- Tracking doesn't stop being useful. If you're on HRT, the same review cadence and record-keeping applies. If you're not, ongoing or new symptoms are still worth a dated record if you ever want to raise them.
Why the stage you're in changes what a record is for
In perimenopause, a record is often building toward a first conversation — establishing that a pattern exists at all. Around the menopause point, it's often about confirming dates and any unusual bleeding. In postmenopause, it shifts toward monitoring what's ongoing, tracking a treatment if there is one, and flagging anything genuinely new rather than assumed-away as "just menopause." The fields you'd record don't change much; what you're trying to answer with them does.
This is general information, not medical advice. HormoneLog is a tracking tool, not a diagnostic or treatment device, and nothing here can tell you whether your symptoms are normal, what they mean, or what you should do about them. Those are conversations for a clinician who knows your history.

About HormoneLog
HormoneLog is an iOS app from Baker Ventures LLC for tracking perimenopause and menopause symptoms and keeping an HRT record: what you took, at what dose, from when, and what changed afterwards. It is built for the appointment, where "it has been bad lately" is worth far less than a dated record of frequency and severity. The app is in development.
HormoneLog is a record-keeping tool. It does not diagnose, does not score you, and makes no claim about symptom relief. The guides on this site link to NICE, the NHS, the Menopause Society and peer-reviewed sources, and say plainly where the evidence is thin. Everything here is free and needs no account.
Questions and answers
What are the stages of the menopause transition, in order?
Perimenopause (the transition leading up to the final period, with irregular cycles and, for most people, the bulk of symptoms), menopause (the single retrospective point 12 months after the final period), and postmenopause (everything after that point).
Do symptoms stop at menopause?
Not automatically or on any fixed schedule. Many symptoms that started in perimenopause can continue into postmenopause, and the useful thing a record shows is whether yours are settling, unchanged, or new — not an assumption that the calendar alone changes anything.
Does tracking still matter in postmenopause?
Yes, particularly because postmenopausal bleeding is a defined reason to seek assessment, and general symptom or HRT-review tracking continues to serve the same purpose it did before.
How long is postmenopause?
It's the rest of life after the menopause point — not a phase with an end date the way perimenopause has one, which is one more reason it doesn't get treated as "finished" once it starts.
