Test line not getting darker?

Is this a good blue dye line?? Took this not too long ago. Didn't show up as dark as my last blue dye a few days ago but to be fair I did drink an energy drink....I got a very faint line on a first response 6 days sooner (posted a few days ago) and since my period is still 3 days away everything else has been negative (mostly cheapies).

Cramping in my hips and lower back like AF is coming 😩 driving me insane lol
