Implantation bleeding?

I had a small amount of blood this am.  And that was it.  I am 6 days away from projected AF and 7 days past ovulation.  Is this implantation bleeding? Anyone else experienced this as an early sign of pregnancy.  I am trying for baby #2.  I had a miscarriage Sept 5 (dnc).  Any similar experiences out there?  Any advice would be greatly appreciated as I am pretty worried.  Thanks!
