My menstrual period has been delayed and has not yet arrived. I used a pregnancy test strip, which consistently showed a faint positive result. What does it mean when a pregnancy test strip consistently shows a faint positive?

A pregnancy test strip consistently showing a faint positive result requires further evaluation. First, check the manufacturing date of the test strip to rule out expiration. Second, consider the possibility of an ectopic pregnancy; in such cases, urinary hCG levels rise more slowly, often resulting in persistently faint positive test results. Additionally, shortly after a miscarriage, pregnancy test strips may also show faint positive results, though these will gradually return to normal over time.
