Is 7-10 days after possible conception too early for an accurate result of pregnancy test?

It depends on the sensitivity of the pregnancy test. Some home pregnancy tests are sensitive enough to detect pregnancy as early as 10-14 days after conception. However, most pregnancy tests are not as sensitive and will not give an accurate result until at least 14 days after conception. If you are testing early, it is important to use a first morning urine sample, as this will contain the highest concentration of hCG. If you get a negative result but still think you may be pregnant, it is important to repeat the test in a few days.
