Heavy Period With Clots: Is It Normal?
Period clots guide
Quick answer
Having a heavy period with clots is common, and small clots are often normal. Clots the size of a quarter or bigger, or clots with very heavy bleeding, are a sign to see a doctor. Clots form when blood collects in your uterus and sits for a bit before it comes out.

Yes, small clots are common. They often show up in the first few days, when your flow is heaviest. They can look dark red or maroon.

- You soak through a pad or tampon every hour for several hours in a row.

What causes a heavy period with clots?
Large clots often come with heavy bleeding. Causes include fibroids and polyps, which are growths in the uterus. Thyroid disease and bleeding disorders can cause them too. Rarely, the cause is cancer. A doctor can find out why.
