Good to know
- You can pause and pick up later where you left off.
- Think of the last four weeks, unless a question says otherwise. An estimate is enough.
- There are no wrong answers. The more honest you are, the more personal your advice.
- You don't have to wait for your blood results: you can already fill in the questionnaire.
