my odd 'period'

Kimberley
I started spotting 8 days before my period is due it has now been 3-4 days and it's still happening. Period isn't supposed to start for another 4-5 days either so I am super early. I have no cramps and barely a flow it's there when I wipe it nothing on a pad. Usually I am heavy for the first 2-3 days then slow down. Should I test??
