Ugh!!!!! :/

Anyone else get two evap lines two days in a row??? The lines showed up pretty late ..... The dollar store test has a lot of color taken 12dpo with FMU... The Walmart cheapie taken 13dpo in the evening.... I took a Frer early afternoon on 13dpo but it was negative! Could these tests be more sensitive.... And possibly take awhile for the positive to show up?? Anyone else experience anything similar to this?? I'm due to start today according to Glow... Guess I'll wait and see what happens.
