I know that there are good RIs who will run the key tests on you, perhaps distantly, and give you a protocol, even for use with another doctor.
The key things were to have a diagnostic hysteroscopy which turned out to be the fibroid and a septum removal, then we had the Chicago lab (SIRM uses and my Dr., who used be at SIRM, and now has his own clinic -- Acacio Fertility in Ca) draw for thrombopilia and a series of immune tests. I have Factor V, VIII, and MTHR, NK Cells (and I am hashimotos thyroid). The treatment is heparin twice a day, baby aspirin, prescription folic acid and intralipids infusion therapy before transfer and after confirmed pregnancy. I am also on viagra suppositories, cause the surgery made it harder for me to get a good lining (nice, that was one thing I had going for me).
It's not fun doing so much but it's not really painful, more just a juggling game with the schedule.
Don't get scared by the book, the treatments are not hard to do. You just need one doc to tell you what to do. If you do not have a local one, I'll bet you can get treatment long distance.
