Have you ever had a real vfl on a blue dye test?

Ca

Worst photo ever. If you can't see it, you won't hurt my feelings. AF is a no show and took this with FMU. There's a thick, blue faint line in person that came up in the time limit. It's faint, but not a squinter. It's darker than last night's test. But, it's blue dye, so it could be meaningless. Has anyone actually had a vfl on a blue dye and actually ended up pregnant??
