Some women take home pregnancy tests early, only to find a faint line, which can cast doubt on whether they are really pregnant or not. The rules say that any line that appears on a pregnancy test, even if it's just a faint line, is considered a positive result.

Why is there a faint line in the pregnancy test? There are many possible reasons why only a faint line appears during a pregnancy test: Testing too early.
