Many people with von Willebrand disease don't know it because the signs are mild or absent. The most common sign of the condition is abnormal bleeding. There are three main types of the disease. The amount of bleeding varies from one person to another, depending on the type and severity of the disease. If you have von Willebrand disease, you might have: 
Excessive bleeding from an injury or after surgery or dental work
Frequent nosebleeds that don't stop within 10 minutes
Heavy or long menstrual bleeding
Heavy bleeding during labor and delivery
Blood in your urine or stool

The need to change your menstrual pad or tampon more than once an hour
The need to use double sanitary protection for menstrual flow
Symptoms of anemia, including tiredness, fatigue or shortness of breath
