Ladies could this be implantation bleeding?

I posted in the general topic as well but always seem to get a better response in this one. My urine test yesterday was negative, blood test was a 2 which is negative. Cramping started today, cervix is high, af is 2 days late. I've never had implantation bleeding before. Could that be what this is?? It was accompanied by a creamy discharge. My back is killing me today, very low right above my tailbone.
