Dye runs and Evaps ahhhh!!

How very annoying I’m 7-8 dpo and has definitive line very clear. Today I went and got frer to test and nothing this was second morning wee I hadn’t drink anything in between and was about 45 mins apart from FMU! Have I still got a chance do you think or deff a evap the line appeared after about 5 mins and did get darker until about 30 mins after test then it’s just stayed the same even this morning!

What are your thoughts?

Thanks ladies x
