BFP test line was lighter today than yesterday...

Question for everyone. I got a positive on Friday morning (11DPO). After that, the line got darker with each morning's test this weekend.

However, this morning I took a test and while it came back positive it was lighter than yesterday. I have had two chemicals since we started trying 6 months ago so I'm afraid it's another one.

But, the one difference I noticed was that my urine this morning was much less concentrated (way clearer) than the other mornings I tested. Could that have impacted the line colors?

Any thoughts or inputs from you guys based on experience would be appreciated. (Tests below for reference)
