[General] Do Vampire Woman get periods? Do Vampires drink Period Blood?

I-I don't know why.. but I've been wondering that for the last two days.. *gags slightly but still wants an answer*

Since Vampires don't reproduce in the same fashion as the living, there is no need for a menstrual cycle.

Most Vampires will not consume menstrual blood for two reasons. First, it is not live blood cells and does not contain the life essence a Vampire needs to survive. Second, it is not pure blood, as it contains other bodily fluids and waste matter that can get caught in one's fangs.
