Riddle me this...

I got my period early.  It was brown at first than bright red with lots of blood clots and then so light i didnt have to wear any sanitaries unless i was exercising.  Bad cramps.  At first my stomach felt like it was stabby and then my right side hurt terribly.  I was very nauseaous and sick all day and then that night i started.  Now my right side hurts now that its ending. Its usually 8 days and this one lasted 5
