Chemical Pregnancy or Implantation Bleeding ? HELP ..

I am 6 DPO and started spotting 24 hrs back - comes and goes couple of times a day / never enough to wear a pad / tiny clots only once or twice . Colour is between pink to orange or red or neon I feel !

Is it IB or CP ?

Every where I read , CP turns out to be a full blown bleeding - that has not started atleast ! Fingers Crossed !!!

I am 10 days to my period now and I have not tested positive yet. All I read says CP happens post 5 weeks since last period , I am on week 3 / CD 21 .

PLEASE HELP !!
