I'm having my first herpes outbreak and aside from the pain I am having a lot of bleeding. My period isn't supposed to start for another 8 days. What could be causing all of this?

Where is it? Is the bleeding coming from the vagina or from the herpes lesions? Herpes is expected to be painful, however, a lot of bleeding is not common unless you have further irritated the area with picking or scratching. Go to your doctor if the bleeding does not stop on its own.
