What this site is, and is not

Menstria is a set of structured ways to organise what you already know about your own body against published criteria. It does not diagnose anything. Bleeding that is heavy, prolonged, irregular or newly changed has many possible causes — structural, hormonal, haematological and systemic — and separating them requires examination and testing. Bring the output to a clinician; do not use it instead of one.

Every calculation runs in your browser. Nothing you type is transmitted, logged or stored.

Where the evidence is genuinely uncertain, these tools say so and show the range rather than inventing a precise-looking number. Where major frameworks disagree, they show the disagreement. Every figure traces to a specific publication, listed in full on the references page.
