Any idea? (Weird period)

Victoria
I started my period like three days ago with no cramping the pain in my pelvic area/ lower abdomen that usually comes with AF isnt there. It started like normal but not near as heavy. I went so work yesterday which is standing the whole 8 hours and it usually causes me change like 3/4 times during work. I came home last night in the same tampon I put on when I got to work.. (I know) it wasn't even full with blood it was more of a clear fluid and barely any blood. If I don't count the day that it started which I usually don't it would be a 2 day period.. Any idea on what's wrong?
