A pregnancy test can detect the pregnancy hormone 7-14 days after conception, because most women do not ovulate until two weeks before your period is supposed to start. It is useless to take a test within five days of your missed period.

You take the test after you have missed one complete cycle. The test will not be accurate any sooner because it takes a month for the hormones to show on the test.
