Evap line or positive?

Yesterday morning I took a test and I couldn’t see a line but later on that night i looked and it’s got a clear line I know it’s within the 10 mins and after that it can be an evap line but I’ve used these tests loads and never even after a few days when im emptying bathroom bin has one shown up a line after the 10 mins they usually end up yellow in the T section from the urine. Please give me your advice? I would have been 5dpo when I took that test that morning

This is what the other ones usually come up like after the 10 mins
