It is possible to thaw a poorly graded or developed day 3 embryo and try to push it to day 5 for transfer. This process is known as "blastocyst culture," where the embryo is cultured in vitro to allow it to develop into a blastocyst.
The success of blastocyst culture depends on several factors, including the quality of the embryo before freezing, the timing and conditions of thawing, and the ability of the embryo to develop in vitro. In some cases, it may not be possible to achieve blastocyst development with a poorly graded/developed embryo, and the embryo may not be suitable for transfer.
It's best to consult with a fertility specialist to discuss your specific case and options for maximizing your chances of success. They can provide more personalized recommendations based on your individual medical history, fertility diagnosis, and treatment goals.
