Your doc does sound encouraging. My RE was quick to remind me after our 2 failed IVFs that just because the embryos passed the genetic biopsies and reached blastosyst did *not* mean they were perfect since genetic screening only has time to check for 8 of the most common chromosomal problems. It was like he couldn't let us feel good about any of the milestones we passed. I think we'd try it again if we could afford it. We're at least going to try another stim and IUI cycle.
Best of luck,
