Overview

When reviewing the following guidelines, take into account how heavy your normal menstrual flow is. Abnormal vaginal bleeding varies depending on what is normal for a particular woman.

• Severe vaginal bleeding means that you are soaking 1 or 2 pads or tampons in 1 or 2 hours, unless that is normal for you. For most women, passing clots of blood from the vagina and soaking through their usual pads or tampons every hour for 2 or more hours is not normal and is considered severe. If you are pregnant: You may have a gush of blood or pass a clot, but if the bleeding stops, it is not considered severe.
• Moderate bleeding means that you are soaking more than 1 pad or tampon in 3 hours.
• Mild bleeding means that you are soaking less than 1 pad or tampon in more than 3 hours.
• Minimal vaginal bleeding means "spotting" or a few drops of blood.
