13DPO, negative tests, no AF, now what?

🙃🙃

AF was supposed to arrive yesterday or today but is a no show. I'm 13DPO but every HPT shows a BFN. I've been using the Wondfo to test this week, and yesterday I broke and used a FRER and still nothing.

Husband has promised sushi and beer as a "consolation prize" if AF shows up. Do I keep testing at this point or should I make reservations for sushi?
