If that faint line appeared
within the time stated in the kit instructions, it is usually interpreted as a
positive pregnancy test, meaning hCG was detected. A faint line can occur in very early pregnancy. Home tests detect hCG but do not show whether a pregnancy is developing normally or where it is located, as explained by the
FDA pregnancy-test guidance.
Seek urgent medical care if there is severe lower abdominal pain, shoulder-tip pain, fainting, or heavy bleeding.
