What Counts as a Heavy Period?
Every woman's cycle is a little different, so it can be hard to know what is 'normal.' According to the Centers for Disease Control and Prevention (CDC) page on heavy menstrual bleeding, a typical period lasts about four to five days. Your period may be considered heavy if:
- It lasts more than seven days.
- You need a new pad or tampon after less than two hours.
- You pass large blood clots.
- You need to change your pad or tampon during the night.
Heavy menstrual bleeding is more common than many people think. The CDC reports that it affects more than 10 million American women each year, or about one of every five women.
What Counts as an Irregular Period?
An irregular period is one that does not follow a steady pattern. The Cleveland Clinic guide to irregular periods explains that regular periods usually last about four to seven days and come roughly every 28 days. Signs of an irregular cycle include:
- Periods that come fewer than 21 days or more than 35 days apart.
- Bleeding or spotting between periods.
- Periods that suddenly change in length, timing or flow.
Heavy Periods vs. Irregular Periods
| Heavy Periods | Irregular Periods | |
|---|---|---|
| Main concern | Amount of bleeding | Timing of bleeding |
| Common signs | Soaking pads or tampons quickly, large clots, bleeding longer than seven days | Cycles shorter than 21 days or longer than 35 days, bleeding between periods |
| Possible effects | Tiredness, shortness of breath, anemia | Trouble tracking your cycle, possible sign of a hormone problem |
Common Causes of Heavy or Irregular Periods
The Mayo Clinic overview of heavy menstrual bleeding lists several possible causes, including:
- Hormone imbalance: Changes in estrogen and progesterone can cause the lining of the uterus to build up and shed heavily.
- Not ovulating: When the ovaries do not release an egg, hormone levels can shift and affect bleeding.
- Fibroids and polyps: These are growths in the uterus that are usually not cancer.
- Bleeding disorders: Conditions such as von Willebrand disease affect how blood clots.
- Some medicines: Blood thinners can make periods heavier.
- Certain birth control: Some intrauterine devices (IUDs) without hormones can increase bleeding.
The CDC also notes that polycystic ovary syndrome (PCOS), a common hormone condition, can play a role. Stress and weight changes can affect your cycle too. If you want to learn more about how stress affects your whole body, read the Prima CARE blog on the long-term effects of chronic stress.
Changes in Your 40s
Periods often become less predictable in the years before menopause. This stage is called perimenopause. Some changes are normal, but very heavy bleeding is not something to ignore. The Prima CARE guide to perimenopause symptoms and when to see a women's health doctor explains what to watch for during this stage.
When to See a Women's Health Doctor
According to Mayo Clinic, you should see a doctor if you have:
- Bleeding that soaks at least one pad or tampon an hour for more than two hours in a row.
- Bleeding between periods.
- Any bleeding after menopause.
You should also make an appointment if you:
- Pass blood clots larger than a quarter.
- Feel tired, weak or short of breath during your period.
- Have periods that last longer than seven days.
- Notice a sudden change in your usual cycle.
These can be signs of anemia or another health issue that needs care. Heavy bleeding with dizziness or fainting needs urgent medical attention.
