Are clots normal during your period?

Here’s what to know

Sometimes they are, and sometimes they’re a sign you should get checked.

When are period clots normal?

Small clots on your heaviest day can be completely normal.

By small, I mean:

  • Smaller than a quarter

  • Only happening for a day or two

This usually just reflects heavier flow during that part of your cycle.

When are clots a concern?

Clots larger than a quarter are a sign to see your gynecologist.

And size is not the only thing that matters.

Other signs your period may be too heavy:

  • You need to change a pad or tampon more often than every 2 hours

  • Your period lasts longer than a week

These are all indicators that something more may be going on.

What causes heavy periods?

There are many possible causes, ranging from simple to serious.

It could be:

  • Your birth control

  • Hormonal changes

Or something more complex, including:

  • Structural issues in the uterus

  • In rare cases, cancer

That is why heavy periods always need to be evaluated.

What happens if you ignore it?

Heavy periods don’t just stay inconvenient, they can affect your health.

One of the most common complications is:

  • Anemia (low iron levels), which can cause fatigue and weakness

What will your doctor do?

Evaluation is straightforward and helps get you answers quickly.

This may include:

  • Lab work

  • An ultrasound

  • Sometimes a biopsy

From there, treatment can be tailored to the cause.

Can heavy periods be treated?

Yes, and there are many options.

Treatment depends on the cause, but the goal is simple:

  • Lighter, more manageable periods

  • Protecting your overall health
