Heavy, average, or light — where does your period fall? Answer three quick questions and we'll give you a score and plain-English explanation of what it means.
Clinically, heavy menstrual bleeding (HMB) is defined as losing more than 80ml per cycle — but the practical benchmark is soaking through a pad or tampon every hour for several hours, passing large clots, or it significantly impacting your daily life.
Could it be something else?
Heavy periods can be caused by fibroids, endometriosis, adenomyosis, PCOS, thyroid issues, or hormonal imbalances. All are treatable. If your flow is affecting your quality of life, your GP can help.
