Vaginal bleeding between periods
Definition Intermenstrual bleeding is uterine bleeding that occurs between menstrual periods.
Alternative Names Abnormal uterine bleeding; Bleeding between periods; Intermenstrual bleeding; Spotting; Metrorrhagia
Considerations Normal menstrual flow lasts about 4 days, produces a total blood loss of 30 to 80 ml (about 2 to 8 tablespoons), and occurs normally every 28 days (+/-7 days). Vaginal bleeding may be something to worry about for women over age 50 (postmenopausal). The risk of malignancy increases with age. Make sure that bleeding is coming from the vagina and is not from the rectum or in the urine. Inserting a tampon into the vagina will confirm the vagina/cervix/uterus as the source of bleeding. A careful exam by your health care provider is frequently the best way to sort out the source of the bleeding. This exam can be accomplished even while you are bleeding. Do not delay getting an exam just because you are currently bleeding.
Common Causes
  • Uterine fibroids or polyps
  • Injury or disease of the vaginal opening (caused by intercourse, infection, polyp,
  • genital warts , ulcer , or varicose veins )
  • Vaginal injury from insertion of foreign objects, from
  • malignancy , or from infection
  • Dry vaginal walls resulting from lack of estrogen after
  • menopause
  • Pregnancy complicated by
  • abortion (spontaneous or induced)
  • Pregnancy complicated by ectopic pregnancy
  • Fluctuation in
  • hormone levels
  • Stopping and starting birth control pills or estrogens
  • Low thyroid function
  • IUD use can cause occasional spotting (if bleeding is slight, it can be ignored)
  • Drugs such as anticoagulants
  • Cervical conization
  • or
  • cauterization procedures
  • Stress
  • Home Care
  • Bed rest is recommended if bleeding is heavy.
  • The number of pads or tampons used over time should be recorded (so that the amount of bleeding can be determined). Because aspirin may prolong bleeding, it should be avoided if possible.
