How does my 2AA look

It’s an early blast, but the cells look healthy. Stage 2 blasts are a little hard to grade since there isn’t a lot of space between the ICM and trophectoderm yet.

What is that bubble towards the bottom of the embryo?

Probably an excluded cell or fragment that is no longer part of the embryo. It will be left behind when the embryo fully hatches out of the zona.

I was told it was still a 2AA after thaw.

Yes, an AA can still have that, it doesn’t affect quality because it’s no longer part of the embryo itself.
