@Ana1234 - Uncontrollable mood swings are generally an exception to the rule and should be treated as a symptom of a medical condition unless that has been ruled out, in my opinion.
There are plenty of medical conditions associated with hormones and the female reproductive system in general that can make "that time of the month" very miserable for some women. I would not blame anyone suffering with the pain of endometriosis for lashing out now and then.
And it's also true, as it says in the article, that there are women who feel surges of happiness or other emotions during their cycle as well. It's a very individual thing.
