Took my test, now I'm confused!

[Leanna5813]

I'm 18 dpo and took a hpt after holding urine for 4 hours. I waited the two minutes and anxiously examined the test. I saw a very faint line, almost a shadow. I can see line in any negative test I take so I didn't trust my own eyes. I asked my husband, sister, brother, and cousin to all take a look. They all saw a faint "shadow" line. This was seen within the alotted time to read results. So I took another test a couple hours later, only held my urine about 2 hours that time. Got a negative. The first test was blue dye, the second was pink. Should I test with fmu tomorrow or wait a while longer? The blue test line has disappeared and instead has a very distinct thin evap line.

Blue dyes aren't very reliable if the line is gone now I would count it as a bfn.
As for testing again it's up to you how long you can hold off.
