When did you stop testing?

Al

These tests are 8-12dpo, all FMU. I had two chemicals this year, one that failed right away and one that lingered for about 6 days. Neither of those ever got this dark so I am feeling hopeful, but I am torn between continuing to test until I get a dye stealer or just stopping now. I know a dye stealer can a take couple of days and I just know I’ll make myself sick with worry if the test looks the same tomorrow as it did today but at the same time, I’ll worry if I stop testing 😥. When do you guys consider yourself safe?
