  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.
10 days: A blood pregnancy test is the most accurate type of pregnancy test. It can detect a pregnancy as early as 10 days after conception. A urine pregnancy test is reliable after you miss a period. Uterine changes take longer and depending on who is doing he exam may be felt at 10-12 weeks after conception.
