Which day would you count?

If I go off last period my next period should be today. All tests BFN. But if I go off ovulation testing my period would be Sunday. It’s never late from a 28 day cycle generally so I’m half expecting to bleed today given the test is negative… but I remembered with my third daughter I was like 3/4 days late before I even had a faint line with her. So I figure I may not be out yet but I guess I’ll see?

Which day would you count being late from ? Today or Sunday?
