How late were you when you got a BFP

I’m 5 days late and I’m worried as I just said it was stress that caused the delay I’ve tested negative a few times. Everyone around me just tells me you haven’t tested positive yet just wait. I’m not totally crazy about being pregnant again but if I am I am. I just rather it be stress right now than pregnancy what do you guys think or is it possible to test a few times negative and then let’s say like 8 days late you get a positive? Now I’m really stressing lol
