Is this positive or a fluke?

[Arkan48]

Hi, I'm usually a 28 day cycle but my cycles have been getting longer over the last 6 months up to a 42 day, I assumed I wasnt due AF until the 17th but I got bored today and did a test and a line came up, I did one 3 hours later with a much fainter/barely there line, thoughts?

A line or 2 lines?

If you had two lines, twice, it's a definite positive. How dark it is is a result of how diluted your urine is.
