Positive result but disheartened

[SunsetVibe]

(History of a chemical and a loss at 5.5w.)

Tested at 11dpo using the easy@home and it was negative, at 12dpo it was vvvv faint, almost made me doubt it. Today at 14dpo it's as per the picture below. It has darkened a little bit, but isn't this too faint for 14dpo with these tests' sensitivity?

I've also had insanely sore breasts since around ovulation which is not normal for me, but I now feel they are softening. AF was due tomorrow.

Should I brace myself for another chemical?
(I know nobody knows for sure, but it would be good to have other people's opinions/experiences).

I only have pics for my current pregnancy (almost 16w) and as you can see it's about the same as yours the day before my period and day of. Didn't really get dark until day 7 of due period and day 8 with a different test.
I've had dark tests day of and resulted in mc and light and dark tests that resulted in 2 dc.
Like you said, nobody really knows. But fingers crossed for you
