Welcome! I can't say I am in the same situation as you (mine is an abnormal tube that is shaped oddly and has tiny polyps - among other things), but I do remember somebody on this forum who had a surgery for basically the same thing. I wish I could remember who it was, sorry! Hopefully they will see your post and be able to give you some information.
Anyway, I think it's great that your surgery was successful
. That's half the battle! I had a lap in November to unblock my tube, and that worked, but we still have other issues.
I hope you get your BFP very soon - GOOD LUCK!
