The amount of bleeding, severity of pain, pregnancy possibility and how long the pattern has lasted help determine the safest route.

Describe what is different from your usual pattern, not only whether a period is early or late.
Flooding, clots, frequent product changes, bleeding through clothes or bedding, or avoiding activities can indicate heavy periods.
