Thin blue line = an evap?

[Kerjack]

So I took a 2 line blue test this morning as I am CD 37 today. And I got a thin faintish blue line before the 2 minute mark (had a timer running). Are thin blue lines common for evaps? Do evaps show up before 2 mins? Bahhhh... I should have made sure it was a pink dye test.... but the bloody box was PINK!... stupid store....

My clear blue tests turned into a thin line before the time limit was up lol x

blue dyes are the devil i had many positives on them without actually being pregnant

When it comes to any lines showing on a blue dye unless there is absolutely no doubt I always suggest testing with a pink or digi. I have seen people (including myself) get the thin blue line and not be pregnant yet I have seen some people get them and it ended up being positive in the end.
