Cycle day 50 line maybe?

[Kinickynicky]

Hi I’m
On cycle day 50 have had bfn after bfn but then last night I just decided to to test on the off Chance as I’ve felt so sick and my boobs are killing my, no sign of af whatsoever not sure if it’s a bfp or not 🙏

This is how they both dried after using fmu today (peed and dashed this morning and been out literally all day) checked them again when I got home. Can evap lines be bright blue? Took a free - bfn :(
