Period blood loss chart for printing off

Each time you change a tampon or towel, place a mark mark in the column against the picture which most closely resembles your tampon or towel. (Some women use tampons, some use towels and some use both when the period is heavy.)
If you have a clot, mark roughly how large it is using different coins as a guide. In the UK for example, the size of a 1p, 2p, or 50p coin can be used.
Flooding means you have blood flow enough to stain your underwear (or worse) despite using a tampon, towel or both. If you have any flooding, place a mark in the flooding section.
The example shows a woman who over one day had five heavily blood-soaked tampons, one moderately blood-soaked tampon, one heavily blood-soaked towel, one moderately blood-soaked towel, and one clot the size of a 50p coin.

What causes heavy periods and abnormal vaginal bleeding?
Whether you're 13 or 53, abnormal or unexpected vaginal bleeding can be a massive source of stress, worry and confusion. But, while it could be an early sign of uterine or cervical cancer, it may also be a sign of something far more benign. The difficulty is knowing how to tell the difference! We speak to specialist gynae nurse Tracie Miles, from charity The Eve Appeal, to find out what your bleeding might be a symptom of, and when you should be concerned.
