Embryo Banking - # to shoot for?

We’re in the process of embryo banking. My baseline for my second retrieval is next week. Due to having more fragile embryos, we’re freezing at day 3. The first round was a few weeks ago and we were able to freeze 4. Hoping for similar if not better results for this next cycle.

Does anyone know if there’s a rule of thumb for how many to shoot for? My dr mentioned 2 embryos per kid if they’re PGS tested. These aren’t obviously so assume the goal would be to bank a lot more than that. Anything your offices have shared with you?

Hoping to not have to do a third retrieval. But we’re open to it and just getting it done with. The retrieval’s seem to be the worst on your body so I’d rather get them done sooner even if we end up not needing all the embryos. Seems like a good “problem” to have. That said... I think three retrievals is my limit!
