Do some women just get faint tests?

[Foxtrotbeta]

All of my tests are positive but faint. Is that just the case for some women? I know I drink a lot of water but the FMU looks concentrated.
I think I am 4+6 but bled a small amount on Friday.
Thanks!

There are instances where it can just be faint.

It also depends on the test you're using. Perhaps try digital CB test. At this stage it should measure 2-3weeks I think.

I'd stop testing after the confirmation though.

Mine were confirmed with blood tests at about 6 weeks, even at week 7 my tests were faint. I do drink a lot of water.
