Weird period

Ok so I just started my period 2 days early. I'm having terrible cramps and feeling sick to a point of throwing up. Now I usually feel a little sick during my period but today I had to leave work early and when I got home I took a 2 1/2 hour nap. I've been drinking lots of water but I've been getting the chills and then I get overwhelmingly hot. Oh also I am bleeding very odd, its not thick and dark like normal its like extremely watery and just like pinkish. Has anyone else experienced this ? I'm going to the female doctor next week. I just wanted some advice.
