I am a week late with AF. The day before I should have gotten it, I took a clear blue digital that came up negative which I figured i might have tested early anyway.. especially with digital. I took a test Saturday morning and was also negative, but it was the test from the Dollar Tree (literally the test was $1) which I heard mixed reviews about. In another app I use it says I’m only 4 days late.. super frustrated! Anyone have advice for the best test to use? Or maybe I just stressed myself out of a period this month.
