Lh lines faint in afternoon HELP!!

So I test around 11am and again at 6pm, but my lines are way stronger in the morning, but way fainter in the evening, which do I go by?? It’s been many days (not a positive yet, but super close to it) idk which to test bc I read being dehydrated can give you a false positive, and my pee is still super dark in the morning, but I also heard drinking too much water can make it a false negative, and I’m more hydrated in the afternoon (even when I don’t drink anything for 3 hours and hold my urine, today it was almost crystal clear like water) so I feel so confused and idk whether to even log my afternoon tests bc I feel like it’s messing with my chart
