Evap line question

Erica

So I took a blue dye test today (not my fav but I found it in my drawer and didn't know I had it- was waiting to test but found that and thought why not)

I'm 7dpo today and I know that's soooo early but I thought whatever bc I didn't know I had it and I knew I would retest with pink dye in a couple days regardless.... I didn't use fmu, I took it the second time I went.... I guess I'm curious about how evap lines work.... within the time frame from the box I looked and I thought I saw the most faintest of lines but wasn't 100% sure bc it was so faint.... half an hour later it was still faint but much darker. The color in my eyes is blue and I read that if it has color it's a faint positive- I also read that it's hard to tell if it's actually blue or actually grey- I very much so feel that it is blue, so I took the test apart and it is blue.

I guess I'm just looking for some advice and maybe someone to tell me if they ever had the same confusion and got their BFP.

Like I said, I will retest in a couple days and I'll be using a frer so it will be a pink dye.....

I would really really really appreciate the help while I have these next few days of waiting in the dark.

Thank you in advance and BABY DUST LADIES!!!!!!
