Large Blood Clots During Your Period? What It Could Mean

You’ve noticed that your periods have changed. The blood clots that appear during your period are getting larger — bigger than a quarter, sometimes significantly larger. Your period may be heavier overall, lasting longer than it used to. You may be soaking through protection more quickly than before. This is not something most people talk about openly, but passing large blood clots during your period is a meaningful symptom that can indicate an underlying condition that deserves attention.

Large clots during menstruation often signal that blood is pooling faster than the uterine lining can process it. When menstrual flow is very heavy, the body’s natural anticoagulants in the uterus cannot keep up, and clots form. The most common structural cause of this in women between the ages of 18 to 45 is uterine fibroids.

At Seamless Medical Centers in Port Arthur, TX, Dr. Zagum Bhatti, Board-Certified Interventional Radiologist, evaluates and treats fibroid-related heavy bleeding for women across the Golden Triangle — Port Arthur, Beaumont, Nederland, Orange, Vidor, Bridge City, and surrounding communities. Patients from western Louisiana including Lake Charles and Sulphur can also access UFE care at our Port Arthur location. Residents of those communities can get Menorrhagia treatment information to see if UFE is right for them.

When Clots During Your Period Are Abnormal

Passing some clots during menstruation is normal, particularly at the beginning of a heavy flow day. Small clots, up to the size of a grape, are common and not typically a concern in the absence of other symptoms. When clots are consistently larger than a quarter — or when they are accompanied by very heavy flow, significant anemia symptoms, or progressive worsening over time — getting evaluated by a doctor is appropriate.

Women in Port Arthur, Beaumont, Groves, and Lumberton who find themselves planning activities around their heavy periods, keeping extra supplies everywhere they go, or feeling exhausted and light-headed during their period are likely experiencing menorrhagia — abnormally heavy menstrual bleeding — that is affecting their daily life and potentially their iron stores.

How Fibroids Cause Heavy Bleeding and Clots

Submucosal fibroids that grow into the uterine cavity significantly increase the surface area of the endometrial lining. When more lining sheds during menstruation, there is more blood to clear. Fibroids also interfere with the uterus’s normal ability to contract and constrict the blood vessels in the endometrium — the primary mechanism by which bleeding is controlled. The result is heavier, longer, and harder to control menstrual bleeding, with larger clots forming as blood pools faster than the natural anticoagulants can process it.

For women in Silsbee, Orangefield, Port Neches, and surrounding Jefferson County communities who have been managing increasingly heavy periods for months or years, understanding what fibroid embolization involves and how it can reduce this level of bleeding is an important step in exploring treatment options.

Frequently Asked Questions About Blood Clots During Your Period

How large is too large when it comes to menstrual blood clots?

Blood clots larger than a quarter (approximately 2.5 cm) are generally considered abnormally large and warrant medical evaluation. If you are consistently passing clots this size or larger, particularly if accompanied by very heavy flow, you should discuss this with a healthcare provider.

Could the clots be causing my fatigue?

Yes. Heavy menstrual bleeding with large clots can lead to iron-deficiency anemia over time, as the blood lost each cycle exceeds the body’s ability to replace it. Anemia from heavy periods commonly causes fatigue, weakness, shortness of breath with exertion, difficulty concentrating, and pallor. If your periods are consistently very heavy and you have been experiencing these symptoms, evaluation should include blood work to check hemoglobin and iron levels.

Is UFE appropriate if I still want to have children?

UFE is generally not recommended as a first-line option for women who plan future pregnancies. For women who want to preserve fertility while treating fibroids, myomectomy — surgical removal of fibroids while preserving the uterus — is typically the preferred approach. Dr. Bhatti will discuss your fertility plans during the consultation.

Do I need a referral to see Dr. Bhatti in Port Arthur?

A referral is helpful for care coordination but is not required. You can contact Seamless Medical Centers directly to schedule a consultation. Bringing your most recent pelvic ultrasound imaging, if available, helps make the consultation more productive.
