Ok this is a kind of weird question but when i was reading breaking dawn i was wondering how does edward and his family cope when bella has her monthly period i mean BLOOD ???

This is Stephanie Meyer's response which you can read on Twilight Lexicon:
Several girls wanted to know if Edward would have a more difficult time being around Bella when she?s having her period. Answer: Yes, a little bit, but he would never say anything about it?much too much of a gentleman. And Bella would be way to embarrassed to ask. (It?s not the same as a cut, though. It?s sort of "dead" blood, if you get my meaning).

OMG I KNOW!!
that's been bugging me thru the ENTIRE series!
i mean, what if she has a bitten cuticle or something, and there's a TIIIIINY bit of blood... that would count too, right?
and sheesh... the period is such a huge thing to overlook.
it kinda ruins the whole series, doesn't it? i mean there's no explaination and she's GOT to be having it (coz she was thinking about it in BD) so i guess it makes the whole series kind of a fluke... right?

you would think that she would like go to her dads
or mom and tell edward to leave her alone for a little .

mmmhhhhhhmmmmm????
i dont really know

well it doesnt mention it in the book because edward is to gentlemanly to mention it. and bella is to embarrased to ask. but the blood doesnt effect him has much a regular blood. because period blood is dead blood.
