Anyone not get a BFP until after 12 DPO?

Courtney

**UPDATE** I'm 12 DPO with all negatives. AF was due yesterday. I've been cramping like the witch should arrive any minute but nothing! Has anyone tested up until 12dpo with negatives and then gotten a bfp?? ---Still no AF in sight and she's 2 days late. Not even any spotting. I think I have a VVFL on a wondfo this AM!
