Abnormal Uterine Bleeding

Abnormal uterine bleeding can occur for a number of reasons, including problems with ovulation, a hormonal imbalance or abnormalities of the vagina, cervix or uterus.

Abnormal bleeding may be:

  • Prolonged — longer than a woman's normal menstrual period
  • Frequent — less than 21 days from the first day of one bleeding episode to the first day of the next
  • Heavier than usual — requiring more than a pad every hour during the heaviest time
