Yes. Vampires can smell menstruation. Vampires will often sneak into public female restrooms, take the tampons out of the receptacles, and suck on them like lollipops.
Irregular menstrual periods can also result, and interest in sex may diminish.
Yes Vampires have periods. Even though they are dead creatures they do have periods. It may come as a shock but all vampired have periods even males.
