How long does the whole covieving a baby take to show up on a test?

It typically takes about 1-2 weeks after conception for a pregnancy test to show a positive result. This is because the body needs time to produce enough human chorionic gonadotropin (hCG), the hormone detected by pregnancy tests. Most tests are most accurate when taken after a missed period, which usually falls around 4 weeks after conception. However, some sensitive tests can detect pregnancy as early as a few days before a missed period.
