Hi. I had a normal period 04/09/2013 - 07/09/2013 and 16/09/2013 I started to spot brown/pink and its very light, with mild cramps. The spotting only last half the day and continues the next day, I have no idea what's happening, my period only due next week. Can someone please tell me what this is...

Does anyone know what this means because I'm getting worried, for this has never happened before..?
