I would suggest taking a second test to be sure, but the line showing up means that the target of interest (ex. pregnancy protein) is present.
Faded or “light” lines can be due to a variety of issues, but basically boils down to lower concentration of target reaching the colorimetric reagent.

Yes, that’s a positive pregnancy test. Any second line visible means it’s positive. But best do another test from another brand to be doubly sure.
