Personally my period puts me in a pretty bad mood and I can get kind of mean but it could be a placebo (I think that's the right word?) effect and that may or may not be all there is to it.
Yeah, I’ve had a lot of responses from people who say their period affects their mood because of cramps and things and I think that’s valid.
I mean, hell, I have pretty terrible cramps myself and I can tell you that when my uterus is doing backflips I am not in the cheeriest mood.
