Abnormal bleeding (Periods)

Abnormal bleeding can occur at any age & has many causes.

A normal menstrual cycle is typically between 24 days and 38 days. A typical menstrual period lasts up to 8 days.

What is ‘abnormal’?

Bleeding in any of the following situations is considered abnormal uterine bleeding:

  • Bleeding or spotting between periods
  • Heavy bleeding during your period (menorrhagia)
  • Menstrual cycles that are longer than 38 days or shorter than 24 days
  • Irregular periods in which cycle length varies by more than 7–9 days
  • Bleeding after menopause
  • Bleeding or spotting after sex

Abnormal bleeding can occur at any age. However, at certain times in a woman’s life it is common for periods to be somewhat irregular. Periods may not occur regularly when a girl first starts having them (around age 9–14 years). During perimenopause (beginning in the mid–40s), the number of days between periods may change. It also is normal to skip periods or for bleeding to get lighter or heavier during perimenopause.


Abnormal bleeding can be caused by a variety of factors.

  • Problems with ovulation
  • Fibroids and polyps
  • Endometriosis
  • Bleeding disorders
  • Problems due to some birth control methods (intrauterine device (IUD) or birth control pills)
  • Miscarriage
  • Ectopic pregnancy
  • Certain cancers

Heavy Periods

Menorrhagia is the term used to define menstrual periods when bleeding is overly heavy or extended for an atypical amount of time. Medically, menstrual periods are considered heavy if they prevent a woman from doing her daily activities.

  • Fibroids
  • Pregnancy complications
  • Some medications
  • Certain cancers


Bleeding is considered heavy when:

  • Soaking through one or more sanitary product during an hour
  • Bleeding for more than seven consecutive days
  • Passing large blood clots during her menstruation
  • Daily routine during is adversely impacted

Women experiencing any of these symptoms or heavy bleeding after going through menopause should schedule an appointment with a physician.


Your physician will make a diagnosis after process of elimination that includes a series of questions about medical history and previous menstrual periods. Your physician also may recommend a blood test, a pap test, an endometrial biopsy, a hysteroscopy or a gynecologic ultrasound.
