Dysfunctional Uterine Bleeding - Symptoms

Symptoms of dysfunctional uterine bleeding (DUB) include:

  • Vaginal bleeding that occurs more often than every 21 days or farther apart than 35 days (a normal teen menstrual cycle can last up to 45 days).
  • Vaginal bleeding that lasts longer than 7 days (normally lasts 4 to 6 days).
  • Blood loss of more than 80 mL (3 fl oz) each menstrual cycle [normally about 30 mL (1 fl oz)]. If you are passing blood clots and soaking through your usual pads or tampons each hour for 2 or more hours, your bleeding is considered severe.

Most menstrual blood is lost in the first 3 days of the period. So excessive blood loss is possible without having exceptionally long periods.
