Possible faint line with fmu then 2 negative in the afternoon ☹

Katie • TTC for baby #1

I took this test this morning with FMU and got what LOOKS like a faint line. I then took a blue dye test and a dollar store test later in the day and they were both negative.

Could the first test just be an evap? Or should I test again in a couple days? So frustrating and so discouraged! ☹
