Evap Lines - do they appear immediately?

[indiaH4]

Or do they show up later?

I am TTC#1 cycle 3.

I'm asking as I have just got a faint line on a test and it showed up within minutes, it's still there an hour later..

I took another test and again, the same faint line. It doesn't show up on the camera though.

Evap lines aren't very common, if the test line is pink/blue, even if faint, then it is a positive. FRERs are the most sensitive, so it's best to test with them. If you've got a line on a less sensitive test, then it will definitely show on FRER.

Can you put a picture up OP? If it's in the time it's not an evap!

No, evaps tend to appear when the test dries later on.

They should show up later!
I remember I took a frer and it came up immediately with a white line which was weird and I was unsure what it meant.. didn't know if it was an evap or not. 2 days later got a faint BFP. The same thing has happened to a few people after a google search.
Not sure if that's similar but sometimes you can get a line or indent if it's too early but there's something picked up. It would appear straight away though.

Camera won't pick it up clearly! Can only see it in real life under light. I was a but surprised when it came up immediately on both tests. I'm going to take another tomorrow with FMU
