Flow naturally varies from person to person and cycle to cycle, but there are some clear signals that a period has crossed from "heavy for you" into "worth having checked."
Signs Worth Mentioning to a Doctor
- Soaking through a pad or tampon every hour for several hours in a row.
- Needing to change protection during the night more than once.
- Periods lasting longer than 7 days.
- Passing clots larger than a coin.
- Feeling unusually dizzy, tired, or short of breath during your period (possible signs of anemia, a drop in iron from blood loss).
Common Causes
Heavy bleeding in teenagers is often related to hormone levels still stabilizing, but can also be linked to conditions like PCOS, thyroid changes, or blood clotting differences. A doctor can identify the cause and offer treatment, which often includes iron support and, if needed, medication to help regulate flow.
This Is Common and Treatable
- Heavy periods are one of the most frequent reasons teens see a gynecologist or family doctor, you would not be the first or the last. Effective treatments exist.
