Weird period??

I started my period 1 week before I was supposed to, normally my period is 2-3 days, but this time is been 5 days already!! The first three days was just spotting and just brown color, the 3 day was brown and a hint of pink and brilliant red. The 4th day was like if I was starting my period, red and I could feel the flow. Today was a little darker but spotting. I'm I the only one that had this happen?? I am a little worried...
