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.
Even the most sensitive urine pregnancy tests (labeled 10mlU/ml) cannot detect pregnancy until at least 3 days after implantation (about 10 days after ovulation). If the first test is negative, take another test a few days later, when it will be easier to detect. Thanks! Not Helpful 164 Helpful 414.
