Blood Clots During Period
Passing small blood clots during your period is common and usually normal. Larger or more frequent clots can indicate heavy menstrual bleeding or an underlying condition.

What causes it
Clots form when blood pools in the uterus faster than anticoagulants can break it down — common during heavy flow days. Larger or more frequent clots can be associated with fibroids, adenomyosis, or hormonal imbalance.

Note clot size (smaller or larger than a 50p/quarter coin), frequency, and which days of your period they occur. Log flow heaviness alongside. Changes over time — more clots, larger clots — are worth noting.
When to see a doctor
See a doctor if clots are larger than a 50p coin, if you are soaking through a pad or tampon every hour, if this is a change from your normal, or if you feel faint or unusually fatigued during your period.
