Safety boundary

This compares practical use cases; it does not determine whether bleeding is medically heavy.

Worked example

What this looks like in real life

For swimming, a standard external pad does not work the same way it does on land, so the tool routes you toward internal options or period swimwear if those suit you.

The best option is one you can use correctly, comfortably and consistently — not the one with the strongest marketing claim.

What the tool cannot tell you

Does not determine whether bleeding is medically heavy.

Every product has its own instructions and change intervals.

Repeatedly soaking through products unusually quickly can be a health question.
