I have never heard of this!

Apparently it's real. In all the years I have had my period, I have never experienced being so sick I can't hardly get out of bed let alone eat, which is what I do when I get my period. Cramps-yes! But, never nausea. Could it be age? I will be 27 next month. I'm just so ill and fatigued feeling. This has been consistent for 3 days. At first, I thought maybe I could be pregnant. Took a test and that was negative, then the spotting finally occurred. So I am just wondering how many women actually get this, and how do you combat it?
