Anyone with BFP on beta day despite BFNs night before??

3rd round of <a href="https://glowing.com/glow-fertility-program">IVF</a> & doc said the 2 blastos he transferred were perfect. HPT today still a BFN. Feeling hopeless & discouraged. Any ladies still get a BFP?? My beta tomorrow is 9-days post 5-day Fresh transfer.
