At first, the line was so faint that it didn't even show up in photos. Looking at the faint line, I wondered if I was just tricking myself or if I was actually positive for COVID-19.
"Faint or dark test lines develop on COVID-19 tests for any number of reasons and shouldn't be used as a predictor of disease severity or virulence," Mann tells Good Housekeeping. "Slight ...
“A faint line on a COVID test means the test is positive,” says infectious disease expert Amesh A. Adalja, M.D., a senior scholar at the Johns Hopkins Center for Health Security.
COVID-19 rapid antigen tests or RATs, also frequently called COVID-19 lateral flow tests or LFTs, are rapid antigen tests used to detect SARS-CoV-2 infection ().They are quick to implement with minimal training, cost a fraction of other forms of COVID-19 testing, and give users a result within 5–30 minutes.
A lateral flow test (LFT), [1] is an assay also known as a lateral flow device (LFD), lateral flow immunochromatographic assay, or rapid test. It is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment.

If your COVID-19 rapid test turns positive, but the line is faint, unfortunately it still means you have COVID. However, a re-test might be in your future.
When more than one well is used there are many possible outcomes based on the reactivity of the antigen and antibody selected. The zone of equivalence lines may give a full identity (i.e. a continuous line), partial identity (i.e. a continuous line with a spur at one end), or a non-identity (i.e. the two lines cross completely).
