Blood Clots During Your Period: What’s Normal and When to Pay Attention

January 13 2026 | Written by Nadia Ladak (She/Her)

Seeing blood clots during your period can be unsettling especially if no one ever explained whether they’re normal. The good news? Menstrual blood clots are common, and for many people, they’re simply part of how the body manages menstrual flow.

That said, there are times when clots can signal something worth checking in on. Understanding what’s normal (and what’s not) can help you feel more confident and informed about your cycle.

What Are Period Blood Clots?

Period blood clots are thickened pieces of menstrual blood and tissue that come out of the uterus during menstruation.

Your body naturally releases anticoagulants during your period to keep blood flowing smoothly. But when flow is heavier or faster than usual, those anticoagulants may not have enough time to do their job, allowing blood to clot before leaving the body.

This is especially common on:

• Heavier flow days (often days 1–2)
  

• Cycles with stronger uterine contractions
  

• Periods following stress, illness, or hormonal shifts
  

What’s Considered Normal?

For many people, small to medium-sized clots are completely normal especially during heavier days.

Common characteristics of typical period clots:

• Dark red or deep burgundy in color
  

• Gel-like or thick in texture
  

• Occur occasionally, not constantly
  

• Show up during heavy flow days
  

If clots are infrequent and your period pain and flow feel manageable, it’s usually nothing to worry about.

Why Do Blood Clots Happen?

Several factors can increase the likelihood of clots:

Heavier Flow
When more blood is shed at once, clotting becomes more likely.

Strong Uterine Contractions
Your uterus contracts to help shed its lining. Stronger contractions can push blood out faster, allowing clots to form.

Hormonal Imbalances
Estrogen and progesterone regulate how much lining builds up. When estrogen is higher relative to progesterone, the lining can become thicker leading to heavier flow and clots.

Circulation Changes
Cold weather, low movement, or dehydration may contribute to slower circulation, which can make clots more noticeable for some people.

When Might Blood Clots Be a Sign to Check In?

While clots are often normal, it may be worth talking to a healthcare provider if you notice:

• Very large clots regularly
  

• Clots accompanied by severe pain that interferes with daily life
  

• Periods that are consistently very heavy
  

• Sudden changes in your usual cycle pattern
  

• Fatigue or dizziness alongside heavy bleeding
  

These symptoms don’t automatically mean something is wrong but they can be helpful signals your body is asking for support.

How to Support Your Body During Clot-Heavy Periods

If you tend to experience clots, gentle lifestyle support can help:

• Stay hydrated to support healthy circulation
  

• Prioritize warmth, especially during colder months
  

• Move gently: light walking or stretching can encourage blood flow
  

• Eat regularly to support hormone balance and energy levels
  

• Manage stress, which plays a role in hormonal regulation
  

These small habits won’t eliminate clots entirely but they can help your cycle feel more manageable.

The Bottom Line

Blood clots during your period are often a normal response to heavier flow and uterine shedding. They’re not something to fear but they are something worth understanding.

Your cycle is full of information. When you know what’s typical for your body, it becomes easier to notice when something changes and to respond with care instead of concern.

Periods aren’t meant to be mysterious. The more you learn, the more empowered you become.
