RN or Nurse Practitioner? If youâre considering a nursing career, you may be wondering what the difference is between a registered nurse (RN) and a nurse practitioner (NP). What is the Difference Between an RN and an LVN?
  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.
So until there is a detectable amount of the pregnancy hormone, the tests canât catch it. The American Pregnancy Association explained that it can take up to 11 days after conception for hCG levels to show up on a blood pregnancy test, and 12 to 14 days post-conception for urine tests. After it's fertilized, the egg can take six to 12 days after ovulation to implant itself into the uterine lining, which is when hCG becomes detectable by a pregnancy test. It also depends on when you ovulate.
