What counts as a large clot?

Clots smaller than a quarter are common during heavier flow. Clots larger than a quarter (about 2.5cm) passed regularly are considered heavy and worth reporting to your provider. A log noting the approximate size and frequency of clots provides useful clinical information.

Will fibroids get worse over time?

Fibroids are hormone-dependent and typically grow during the reproductive years and shrink after menopause. During reproductive years they may grow, stay stable, or occasionally shrink. There is no way to predict individual behavior. Tracking whether your bleeding is getting heavier cycle over cycle, staying stable, or improving is useful data for monitoring.

If I track my bleeding, what should I specifically measure?

The most useful measurements: how many pads or tampons per day at peak flow, how many hours each piece of protection lasts before it is fully soaked, whether you are using double protection (pad plus tampon simultaneously), how many days are heavy versus light, the size and frequency of clots, and any nights when you had to wake up to change protection. Even approximate answers to these questions are more useful than 'very heavy.'

Is fibroid bleeding data private?

Yes. Heavy bleeding, fibroid diagnoses, and associated reproductive health data are sensitive. Apps storing period data on company servers have shared it with advertisers (Flo Health, FTC 2021) and can produce it under legal compulsion. An on-device tracker keeps your bleeding logs on your device only, with no corporate record of your health history.

Heavy Bleeding From Fibroids: How to Track and Document It

Fibroids cause heavy periods by disrupting the uterine lining. Learn how to log flow volume and patterns to make your doctor appointment more useful.

Why Fibroid Bleeding Is Worth Tracking Specifically Heavy menstrual bleeding from fibroids is one of the most common reasons people seek gynecological care. It is also one of the areas where patient reported data most directly changes what a provider can offer. Ultrasound shows the size and location of fibroids. It does not show how much they are affecting your daily life, whether you are developing anemia, whether the bleeding is getting worse, or what your quality of life looks like over a typical month. That information comes from you, and having it documented makes the difference between a productive appointment and one where the provider is working from a general complaint. This guide is for educational purposes only and is not a substitute for medical advice. How Fibroids Cause Heavy Bleeding The uterus sheds its lining during menstruation through a combination of prostaglandin driven contractions and a precisely regulated local clotting process that prevents bleeding from becoming excessive. Fibroids interfere with both. Submucosal fibroids, which protrude into the uterine cavity, disrupt the surface of the lining and affect local clotting factors. The lining cannot shed and
