When is the LATEST you got a bfp?

Cristina

My period is 3-5 days late it never lands on the exact day it's due, but it should be here by now. I'm cramping a little, took an unhopeful test, got a bfn.

I'm thinking that if I'm pregnant, I would've got a bfp.

For the sake of hope, did anyone get a LATE bfp?
