Heavy Flow Check
By the eva team · · 2 min read
Periods naturally vary, but bleeding may be considered heavy when it lasts longer than seven days, requires very frequent period-product changes, causes repeated leaks or interferes with everyday activities. Heavy menstrual bleeding can also contribute to iron-deficiency anaemia. This EVA self-check helps you notice and describe your flow pattern, but it cannot diagnose the cause.
1. Could My Period Flow Be Too Heavy?
One heavier day does not always mean something is wrong. However, bleeding that repeatedly causes rapid product changes, leaks, night-time changes or disruption to school and normal activities should be checked.
2. How Long Does The Bleeding Last?
Bleeding that lasts longer than seven days can be one sign of heavy menstrual bleeding. A period that has recently become much longer than your usual pattern is also worth recording and discussing with a healthcare professional.
3. Notice How Often You Change Products
Needing to change a pad or tampon every one to two hours, emptying a menstrual cup unusually often or repeatedly soaking through a product in about an hour can be signs of heavy flow.
4. Leaks And Night Changes Matter Too
Repeatedly bleeding through clothes or bedding, waking during the night to change a product or needing two period products together are useful signs to record. Heavy flow also matters when it stops you from following your normal routine.
5. Large Clots Can Be Part Of A Heavy-Flow Pattern
Small clots may sometimes occur during a period. However, repeatedly passing larger clots alongside flooding, prolonged bleeding or very frequent product changes may be part of a heavy-flow pattern that deserves medical assessment.
6. Heavy Flow Can Affect Your Iron Levels
Losing a lot of blood over time can contribute to iron deficiency or anaemia. Possible signs include unusual tiredness, weakness, headaches, dizziness, difficulty concentrating or feeling short of breath during everyday activities. A healthcare professional may recommend blood tests.
7. Some Bleeding Patterns Need Urgent Help
Seek emergency medical care if you are changing pads or tampons every hour for more than two hours and also feel dizzy or light-headed, short of breath or have chest pain. Tell a trusted adult immediately and do not remain alone.
8. Track The Pattern And Ask For Support
Record how long the bleeding lasts, how often you change products, whether leaks or clots occur and how the period affects your energy and routine. This information can help a healthcare professional assess the flow and decide whether tests are needed.
