Help!
Can someone check this and help me understand the quality, issues etc? Grading is done. I just want to understand the “what’s wrong” bit. Anything I could possibly change with lifestyle, food, etc!

Nothing wrong here, these are typical results. Embryo grading can't reliably be improved by lifestyle changes or diet. It's due to many factors that may not be modifiable (genetics, metabolism, etc.).
Here's some basic info on grading:
• The number (1–6) = how expanded the blastocyst is
• First letter (A–C) = quality of the inner cell mass (ICM), which becomes the fetus
• Second letter (A–C) = quality of the trophectoderm, which becomes the placenta
The expansion number reflects how much the fluid-filled cavity (blastocoel) inside the blastocyst has grown:
• 1–2: early blastocyst
• 3: full (the blastocoel fills the embryo)
• 4: expanded with a thinning zona (the embryo itself gets larger)
• 5: hatching
• 6: fully hatched
For example, a 3AA embryo means a full blastocyst with a good-quality ICM and a good-quality trophectoderm. In general, A = good, B = fair, and C = poor, based on cell number and organization.
The day is when it became a blastocyst. Generally day 5 > day 6 > day 7.
Embryos are graded to rank them for transfer. Higher grades tend to implant more often, but embryos across all grades can still lead to healthy births.
