Are you a moody bitch? Good news! You can now blame it on your entire menstrual cycle, not just on PMS! According to Australian researchers ,moodiness, stress and depression, are present all month, fluctuating throughout the average 28-day cycle. Apparently, stress levels are highest on day one of the cycle, while depression and anxiety are a problem during the PMS period. Researchers also found that it's more helpful to exercise than it is to cry and eat chocolate when experiencing premenstrual mood swings. These Australian researchers are assholes. But that's just my menses talking! (Thanks to blood sister Emily Gould for finding our fave period graphic in the first place.) [NEWS.com.au]
