How common are false negative pregnancy tests?

The most common reason for a false negative is that you took the test too early. Even if your period is late according to your typical cycle, you may have ovulated later this month. Another possible reason for a false negative is there isn’t enough hCG in your system. Pregnancy tests look for the pregnancy hormone hCG.

Can you be too pregnant for a pregnancy test?

Yes! Home pregnancy tests can give false negative results. As Dr. Roshan explains, a woman’s hCG level doubles every 48 to 72 hours, so if you really are pregnant, it won’t be negative for long. Take another test in a few days—or around a week after your missed period—and you can trust the results.
