Is it possible to be pregnant but your test says negative?

Answer 1

Pregnancy tests can have false negatives (you're pregnant, but the test says you're not) and false positives (you're not pregnant, but the test says you are). Especially if you take a pregnancy test very early in the pregnancy, when your body isn't making enough of the hormones hCG that the pregnancy tests test for, the test could say you're not pregnant even though you are.
