i mean like in the books and movies they can smell blood....so why not period blood...i don't know ..that is why i'm askinglol I don't think they can. :S cus in the books none of the girls have their periods.What a bizarre question, but... Yeah, why not? Normal humans can smell such things, it would only make sense that a vampire would be able to too.why not i can sometimes, and im no vampire!Ha! of course we can.

Hollywood gets it wrong frequently or leaves out little details such as that one.WTF....................... R U PSYCHO!?!?!
