Vaginal bleeding is any bleeding through the vagina, including bleeding from the vaginal wall itself, as well as (and more commonly) bleeding from another location of the female reproductive system, often the uterus. Generally, it is either a healthy physiologic response during the non-conceptional menstrual cycle or is caused by hormonal or other organic problems of the reproductive system, such as abnormal uterine bleeding. Vaginal bleeding may occur at any age, but always needs investigation when encountered in children or in postmenopausal women. Vaginal bleeding during pregnancy may indicate a possible pregnancy complication that needs to be medically addressed.

Blood loss per vaginam (Latin: through the vagina) (PV) typically arises from the lining of the uterus (endometrium), but may arise from uterine or cervical lesions, the vagina, and rarely from the fallopian tube. During pregnancy it is usually but not always related to the pregnancy itself. Rarely, the blood may arise from the urinary tract (hematuria), although most women can identify the difference. It can also be a sign of vaginal cancer or uterine cancer.

There are many potential causes for abnormal vaginal bleeding.

Bleeding before the expected time of menarche could be a sign of precocious puberty. Other possible causes include the presence of a foreign body in the vagina, molestation, vaginal infection (vaginitis), and rarely, a tumor.
