I posted this on the TTC forum as well... but wanted to post this here too since I get SO many BFN's. So does anyone know why after a pregnancy test sits out for a while it can turn positive? It's just evil to take a test and wait the allotted time and BFN and then see it in the trash 2 hours later and it looks like a BFP! UGH!!!
What are evaporation lines?
Evaporation lines, as the name suggests are caused due to evaporation of the urine in then test area. These are lines that shows in the result window of the test, exactly where a positive sign would be. An evaporation line develops when the urine on the test area begins to dry, leaving a faint, usually colorless line. Evaporation lines appear to show up (or not show up) as a result of the composition of the particular urine specimen and they may appear on any test regardless of brand.
