Line on frer test from 2 days ago

[Redyellowpinkgreenpurple]

I’m going crazy here.
I am 5 days late, feel sick, sore boobs, completely wiped of all energy.
Every pregnancy test has come back negative.
I’ve just found a frer test from 2 days ago and there is a faint line?! Is this normal?

It might be an evap line. I've had some in the past that I've picked up after a few days and there's a line but I wasn't pregnant.

Can you take another test to be sure?

Forgot to say I took another test today which was negative but not FMS.
The old one was FMS but I’m not sure how much of a difference that makes.
