Anyone had success with a poor quality blastocyst transfer?

And I mean really poor... The one I had transferred for my first fresh transfer yesterday was only at stage 2 (of 6) and was not even developed enough to have a grade of letters with it 😣😭

We were heartbroken, especially as we got the call today that none of our other embryos made blastocyst stage, so we have nothing to freeze.

So this is our only chance, but it feels like such a tiny chance given it was such an early blastocyst. Has anyone else had any success with a Stage 2 or poor quality blast transfer?
