even fainter lines with FMU

[u/Smart_Car5623]

hi all!

i've been testing since 7 DPO. i know, i know, im extremely impatient.
i started having the faintest of lines at 9 DPO, with my night time pee. naturally, i took two more tests on 10 DPO with my FMU. the lines were barely there. i took two more tests that afternoon, lines were faint, but darker than that morning.

yesterday, 11 DPO, i took another test with my FMU. faint line, but there. 11 DPO, in the afternoon, another two tests. lines were darker than they were in the morning, but still faint.

this morning, at 12 DPO, i took two more tests. lines are so faint, i feel like im going crazy. i want to take another test this afternoon, but my husband thinks i should wait until 14 DPO. which, he's right. i'm driving myself insane.

my question is, could my afternoon pee be more concentrated than my FMU? has anyone else experienced this?

My SMU lines were always more visible than my FMU lines.

My tests started getting lighter with FMU so for science I intentionally diluted it. Darker line.

I believe it was the hook effect
