Why are girls so moody when they have their periods?

Women are emotional. Way their brains are wired. Hormones affect that and your monthly are triggered by your hormones. Hormones don't know to stay in one area in a body when your heart pumps everywhere. So needless to say, your brain has blood flow, thus hormones affect your brain triggering emotions.

It's hormones and it doesn't really feel good to be bleeding down there and have pads on and have cramps. You just feel gross. And again hormones.

Because their hormons would be working ....and u would get really angry bcz ur in pain....

It's all about the hormones...

Its a personal thing it varies with the individual

Hormone related stuff

I try not finding out and leave them before i become there target lol

Hormones kick in overdrive.

It's there hormones.

Hormones, cant be heled.. Just something that happens

Because most of the time the pain is unbearable so we get annoyed easily and want to take it out on everyone.

Because the week before you go threw  what is known as PMS ..why? Well because its how GOD created humans

In my opinion its because the girls think that there is something wrong with them. But its like a hyprcondriacs or however you spell it. Its all in you head!

Because it is irritating aint it the blood , the cramps come on did you realy have to ask that or are you craveing some attention?
