2week early but spotting

Hi as anyone at all been spotting 12days after there last period? I'm 2weeks early on my period I've always been a week late since I could remember... I keep getting a jab pain in my left side just under my ribs.. Haven't been to doctors yet as the appointments were full up.. I started spotting 2nd January & didn't spot on the 3rd but spotted on the 4th.. But only when I wipe.. Has anyone had the same situation? 
Btw I did a pregnancy test the other day & came back negative.. I'm gonna try get in to doctors tomorrow...
