Hi Huang - In order to help you, can you confirm which product you are using? Is it a pregnancy test with lines?
If so, are you referring to the control window? If there is no line in the control window then you cannot rely on that result. It might be easier if you calls us and mention reference number 001804356A. The careline number is on the side of the box.
