Intro and question: Curvy cervix or cervical stenosis?

Hi everyone - I am not yet a "success" story, but I was wondering if anyone could let me know if they've experienced something similar to what I'm going through right now. 

First, my brief story. I had to have a D&C after a missed miscarriage last year. It was an aggressive D&C which required a couple of stitches to be placed in my cervix for repair. Fast forward to this year and lots of BFNs later DH and I have started to see an RE. The first RE we visited attempted two diagnostic hysteroscopies but both failed. He couldn't locate the cervical opening. His recommendation was to do some sort of laparoscopic surgery or gestational surrogacy. So, we got a second opinion. Dr. #2 has located what he believes to be my cervical opening (lots of scar tissue around it) but cannot pass a thin wire through without causing lots of pain. He says it could be caused by lots of things, so the plan of action now is to do an 'exploratory' hysteroscopy and HSG under conscious sedation in mid-August. He says what could be going on is something like a curvy cervix, or cervical stenosis and he said that one of the things that he could do is place a stent in the canal. He'll have to just make that call when we're performing the procedure. He'll also do all the diagnostic stuff we'd do during an office HSG to see if there's anything else causing the IF.

So I guess my question is whether anyone out there has experienced something like this? What did you go through to repair it? What was your experience after repairing the issue? Was this one of the issues causing IF? How did you get pregnant afterwards (IUI/IVF)?

Thanks!
