AF 1 day late and BFN

Alicia
She is officially late so I decided to test and another BFN😔 I'm never late, typically a day early and I haven't been stressed so I don't understand😫 I edited on glow saying she was late and glow moved AF to Friday. Guess I'll have to retest Friday if she still hasn't come by then. Have any of you ladies had similar problems like this but got you BFP later? 
UPDATE: glow even changed when my fertility window was along with a higher cover line for my BBT? It now was I am only 11dpo rather than what I thought I was at 13dpo..
