Positive or evaporation line?

Period due tomorrow (or Friday - as glow & FF have made two different predictions). Tested with a FR rapid result with FMU. No line was clearly seen at 1 minute, started to show up after about 2, and has gotten more pink since. I would immediately think evap line but i read any color means HCG must be detected. The last picture is clearly showing pink. The test instructions say not to use until after missed period but i mixed the test up with early response. Progression of pictures listed below. Picture two includes an opk that i also tested with FMU out of curiosity. So confused!
