Do the darkness of pregnancy test matter?

So based on last menstruation cycle I should be 6 weeks looks like I'm only on week 5

However when I took a pregnancy test it came out super dark right away vs. Wen I got pregnant last year the test was light and got darker with time and based on my last menstruation weeks made sense.

Does this mean anything ?

I know it sounds like a stupid question but it this normal?

Has this happened to u guys plz comment
