Test line lighter at night?

Question

Hey girls, I've been very excited about my BFP, but being crazy like I am, I took another one this afternoon and then about 20 min ago. The lines are still there, but *much* lighter. Cause for concern or does evening cause lighter tests? The tests below are all from today. 6am (purple hcg), 330pm (middle) 10pm (third test, on top)
Anyone have advice?

Answer

How did this work out Ashley? I just had lighter fmu tests after darker vfl positive last night and i am stressing badly, please let me know?

Answer

Your hcg levels are likely to be less concentrated later in the day because your urine is more diluted due to consumption of food and liquid throughout the day. Pregnancy tests read the hcg in your system, which is why they typically day to use your first morning urine - it's less diluted in the morning and contains a higher concentration of hcg. So don't worry.  :)

Answer

Your FMU is better because your levels are built up, at night it's not and your pee is diluted
