That depends on whether you're using a urine test (the most common kind) or a blood test. All pregnancy tests measure the amount of human chorionic gonadotropin (hCG), the pregnancy hormone, in your body. But the two types of tests differ in how (and when) they detect it.
Home pregnancy tests are urine tests. They detect the amount of hCG in your urine, but only when it reaches a certain level. Some home pregnancy tests are more sensitive than others. More sensitive tests may be able to detect low levels of hCG a few days before your period is due.
However, whether you use an ordinary or a more sensitive home pregnancy test, if you use it too early in pregnancy the amount of hCG in your urine may not be high enough for a positive result. Almost all urine pregnancy tests will give you accurate results if you test at around the time your period would normally be due; about two weeks after you ovulate.
A test may be negative for several reasons: you may not be pregnant, or you may have ovulated later than you thought (and so not be far enough along for the test to detect your hCG). In a small number of women, hCG levels can be very low and this may also affect the outcome of pregnancy tests.
The blood test for pregnancy measures the amount of hCG in your bloodstream, not your urine. Blood tests can measure much smaller amounts of the hormone, and so can detect pregnancy earlier than urine tests, usually about six to eight days after ovulation. However, these are only available through your doctor who is unlikely to offer one unless you have pressing medical reasons to know quickly whether or not you are pregnant.
