In your shoes, I would just tell your RE you need to think about next steps and go see what Dr. Copperman or Palter has to say. Lots of ladies/couples need time off to decide what they want to do next during their ttc journey, so that shouldn't surprise him.
Now, I had assumed that it would be months of healing, but when the doctor at GIVF had me back for my follow-up visit after my hysteroscopy about six weeks after the procedure, I asked him when I could cycle, and he said, "You're as good as you're going to be. You can start whenever you want." Now, that scared me, too: was he saying that if I *didn't* move quickly, I'd risk the scarring reoccurring? (Because, at that time, my husband announced that if I wanted kids, we'd have to divorce.) So, I don't know what they'll tell you.
Like me, you have banding, but in a more critical part of the womb that is more likely to prevent implantation or cause m/c. For my own part, I really wonder whether my surgery was necessary -- it was banding in the upper corner of the ute. They'll have you on HRT to help heal the wounds.
If you got the "A" list, then I guess you signed on to the ashermans.org, so these are probably good questions for that list.
GL, and keep us posted!
