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.
HCG, the âpregnancy hormoneâ, is present in your blood right after conception, but it wonât be detectable on a pregnancy test until after the egg attaches to the uterus during implantation. At the earliest, a pregnancy test will not show up positive until around 9 or 10 days past ovulation.
