The problem is that even if the embryo has implanted and you are pregnant, the embryo produce such small quantities of HCG for the first few days after it implants ( remember that it's just a microscopic ball of about hundreds of cells or so at this time), that it's not possible to detect this HCG in the blood . To be able to detect the HCG in the urine will take even more time, which is why you need to be patient.
