Abnormal vaginal bleeding

Abnormal vaginal bleeding is unexpected bleeding from the inside of the vagina. What is considered abnormal varies, depending on what is normal for a particular woman.

Examples of abnormal vaginal bleeding include bleeding:

  • When a woman isn't expecting her menstrual period.
  • After sex.
  • When a woman's menstrual flow is lighter or heavier than is normal for her.
  • At an unexpected time of life, such as before age 10 or after menopause.
