Is PMS a Myth? There's an 85% Chance the Answer is Yes

I fully know this is a minefield, but here are the results of some recent scientific studies...  So I pose the question; IS PMS REAL OR A MYTH???

According to a new study of other studies . . . yeah, I know how annoying that sounds . . . PMS just might be a MYTH.

 --A team out of the University of Otago in New Zealand reviewed 47 different scientific studies on PMS.

 --And only 15% of the studies found that "classic" PMS is real.  Meaning a woman's mood got worse as her time of the month approached, then got better once it started.

 --Another 38% of the studies found that premenstrual syndrome is really just menstrual syndrome . . . so, a woman's mood does get worse, but it doesn't go away as soon as her period starts.

 --Of the rest of the studies, another 38% found there's no association between a woman's mood and her cycle . . . and 9% found a woman's worst moods happen OUTSIDE of the traditional PMS period.

 --So if 85% of studies have found that classic PMS doesn't really exist . . . why is it still such a widespread idea?  The researchers think it may be psychological.  If you BELIEVE your mood swings badly right before your period, it's more likely to happen.
