When women have their periods or are about to get their periods, how many of them actually have bad moods due to hormones?

First off, let me apologize for the awkward wording of the question.

There seems to be an obsession with the moods women have while they have their periods. A woman is angry around that time of the month and it is assumed to be a result of PMS or the period itself. I don’t experience any kind of mood swings but I do have the kind of cramps that could take out a herd of rhinoceroses. Sometimes, I’m a little testy because of this. This is not hormones, this is pain which makes anybody angry whether male or female, whether on a hormonal roller coaster or not. I also know some women who don’t like having people tiptoe around them so they also get a little angry at people.

This leads to my actual question. How many women experience mood swings due to hormones?
