What could possibly cause such a horrible period?

That’s an important question to get answered.

When you know the source–the root cause of your heavy periods–you can confidently choose a treatment pathway that supports you.

When it’s not just a period

Despite all the pain and suffering it causes, you’ll be relieved to know that Abnormal Uterine Bleeding is rarely a sign of cancer for premenopausal women.1

These are the most common causes of AUB in women of reproductive age:

What are endometrial causes?

If you have heavy menstrual bleeding with regular menstrual cycles and no other causes can be identified, you may be diagnosed with Endometrial dysfunction, or AUB-E.

This diagnosis suggests there are irregularities in hormone levels during the shedding and repairing of the Endometrium, which can lead to endometrial tissue that is thicker than normal, resulting in a heavy and long period, often with large blood clots.

AUB-E is an exclusion diagnosis. Meaning, fibroids and polyps (and other common causes) have been ruled out as the cause of AUB.

Signs and symptoms of AUB-E

Heavy menstrual bleeding

Periods with clots

Long periods (7+ days)

Bleeding between periods

What are fibroids?

Fibroids are dense growths and can be within the walls of the uterus, outside the uterine cavity, or protrude into the uterine cavity. They are muscle and fibrous connective tissue and are generally smooth and rounded in appearance.

Did you know?

Did You Know...

By age 50, more than 80% of Black women and nearly 70% of White women will experience fibroids.1

You may have a single fibroid that is tiny and have no symptoms. Or you may have a big fibroid that is larger than your actual uterus and have pain in your back and legs. You can even have clusters of them.

And they’re not soft. They can be hard like a baseball or golf ball. Consider the size of your uterus (approximately 3” x 2” x 1”) and its location (nested next to your colon and intestines and on top of your bladder) and now you can imagine how fibroids cause so many problems.

Those intense cramps and aches are not your imagination.

Types of fibroids

Signs and symptoms of fibroids

Heavy menstrual bleeding

Menstrual periods lasting more than a week

Pelvic pressure or pain

Frequent urination

Difficulty emptying the bladder


Backache or leg pains


Frequent, unpredictable periods

According to the American Journal of Obstetrics and Gynecology:2

Women wait an average of 3.6 years before seeking treatment for fibroids

%saw 2 or more healthcare providers for diagnosis
%reported missing work due to symptoms
%believed symptoms hindered their career

Women expressed a desire for:

treatments that do not involve invasive surgery%
treatments that preserve the uterus%
treatments that preserve fertility%
(under 40 years of age)

Good news. Living fibroid-free is no fantasy.

What are uterine polyps?

Uterine polyps are composed of endometrial cells and grow in response to circulating estrogen. They form on the lining of the uterine cavity and are attached to the uterine wall by a large base or a thin stalk. While they usually remain inside your uterus, they can sometimes be found in your cervical canal, vagina or blocking your fallopian tubes.

They range in size from a few millimeters—no larger than a sesame seed—to several centimeters—golf-ball-size or larger.

(Remember your uterus is approximately 3” x 2” x 1”)

Signs and symptoms of uterine polyps include

Irregular menstrual bleeding — for example, having frequent, unpredictable periods of variable length and heaviness

Bleeding between menstrual periods

Excessively heavy menstrual bleeding

Vaginal bleeding after menopause


Signs and symptoms of uterine polyps include

Polyps can be removed using fast, safe, minimally-invasive, in-office treatments
