You may obtain inaccurate results that are either falsely positive or falsely negative. Errors can result from how you collected the sample, being too early in the pregnancy to detect hormone changes, the time of day you collected the sample  (urine sampled first thing in the morning is best), or effects of medications you take.

One study showed that women had difficulty following the instructions on the package insert. In this study, many positive-for-pregnancy samples showed negative results (inaccurately).
