Well, that's why FertilityTies is here to end all controversy...
Implantation at the earliest happens on 5dpo, 6dpo usually is when the embryo finally makes it to the uterus (it takes it about 6 days to travel down the fallopian tubes)
Implantation can then take upto 3 days once inside the uterus, hence I say that hCG in blood can be detected starting about cd9 or 10 at the earliest..
