  Answer     A blood test should be able to pick up the HCG in your blood at about 7 days after conception.     Some pregnancy tests say they can pick up â¦ HCG in your urine from about 7-10 days after conception, but most tests you have to wait to about 14 days-when your period is due.
A positive pregnancy blood test first happens about 3-4 days after implantation bleeding and about 4-5 days before a missed period. T he early urine home positive pregnancy test (HPT) can usually detect pregnancy 6-7 days after implantation.
