It can be hard to describe premenstrual symptoms from memory alone. NHS guidance suggests keeping a diary for at least two menstrual cycles. The aim is to explain timing more clearly at an appointment, not to diagnose yourself.

## Use the same three questions each day

Briefly answer: “What did I feel, how much did it affect my day, and was there menstrual bleeding?” Use a few familiar words or a consistent severity scale. Leave a missed day unknown instead of filling it later with a guess.

## Do not record only premenstrual days

Comfortable days also help show a pattern. Note when symptoms begin and ease, and how sleep or daily plans are affected. Keep predicted period dates separate from recorded bleeding. A calendar colour cannot diagnose PMS or PMDD.

## Bring a concrete example to the appointment

Prepare an example such as: “On these two days I struggled to concentrate; this changed after bleeding began.” Do not delay seeking help to complete two cycles if symptoms affect your life. Seek prompt support for severe emotional distress rather than assuming the cycle explains everything.

## Do not choose treatment from the diary

A clinician considers symptoms, timing and other possible explanations together. Do not start hormones, medicines or high-dose supplements based on the diary. Review private details before sharing it and select the parts needed for the conversation.
