Track your periods, your main symptoms and anything you take, for at least two to three months. In perimenopause doctors diagnose mainly from your cycle and symptoms, not from a blood test, so a simple record of what happens and when is one of the most useful things you can bring to an appointment.
In short
- Over 45, perimenopause is usually diagnosed from your symptoms and cycle alone.
- Track bleeding (dates and how heavy), your top symptoms, sleep, mood and any medicines or supplements.
- Two to three months of notes show a pattern that memory alone often misses.
Why track symptoms in perimenopause?
Because your story is the main test. NICE and the European Menopause and Andropause Society (EMAS) both say that in healthy women over 45, perimenopause and menopause are diagnosed from symptoms, without blood tests. Hormone levels swing from week to week, so a single result can look normal even when you feel far from normal.
Symptoms also come and go. Without notes it's easy to forget the bad week once it has passed, or to miss that sleep, mood and headaches always get worse in the days before a period.
What should I track?
EMAS lists what a doctor needs to know when assessing menopause symptoms. A useful diary follows the same list:
- Periods: start and end dates, how heavy the bleeding is, and any spotting between periods or after sex.
- Hot flushes and night sweats: how often, and whether they wake you.
- Sleep: time to fall asleep, night waking, how rested you feel.
- Mood and mind: anxiety, low mood, irritability, brain fog.
- Body: headaches, palpitations, joint or muscle aches, dry or itchy skin, vaginal dryness, bladder changes.
- Medicines and supplements: name, dose and when you started or stopped.
- Your own notes: alcohol, stress, illness or travel that might explain a bad day.
Keep it short. A quick rating (none, mild, moderate, severe) is enough.
How long should I track?
Aim for at least two to three cycles. Perimenopause changes slowly and cycles can be irregular, so a few months show the pattern better than a few days. If you start or change a treatment, keep going: your notes help you and your doctor see whether it's working.
How do I use my notes at the doctor?
Bring a one-page summary, not a full diary: how your cycle has changed, your three most bothersome symptoms, what you take, and the questions you want answered. Our guide How to talk to your doctor about perimenopause has a checklist of questions.
When to see a doctor
You don't need to finish a tracking period before getting help. See a doctor promptly if you have very heavy bleeding (for example soaking a pad or tampon every hour, or passing large clots), bleeding between periods or after sex, or palpitations with chest pain, breathlessness or fainting. More on bleeding in Heavy periods in perimenopause.
Always get checked if you have any bleeding after 12 months without a period.
If you have thoughts of harming yourself, seek help the same day.
Frequently asked questions
What's the best way to track perimenopause symptoms?
The one you'll keep using. A notebook works; an app makes patterns easier to see and can turn your notes into a summary.
Do I need to track every day?
Daily is ideal for bleeding and sleep, but a short check-in when something happens is far better than nothing.
Should I track if my periods are still regular?
Yes. Symptoms like night sweats, poor sleep or anxiety can start while your cycle still looks regular, and notes help link them to your cycle.
Can tracking tell me if I'm in perimenopause?
No diary can diagnose you. It gives your doctor the information they need to do that.
Your diary, ready for your doctor
Pausie lets you log your periods (including how heavy), symptoms, medicines and supplements with doses in a few taps. When you have an appointment, it creates a PDF summary with your cycle, symptoms, conditions, medications, labs and your questions. No account, and your diary stays on your phone.
