The main reason: The most common cause for the wrong result is to use the wrong technique, or expecting the test to detect pregnancy beyond the period of time it was designed for.

Follow directions: Home pregnancy tests generally become positive when you're about 1 week late with respect to your period. If it's negative, repeat in 1 week.
