Well it could probably be lots of other things but many people on this board, myself included, have experience with immune issues. So that's what we tend to think of for otherwise "unexplained" cases. Though yours is not classic since you had a second healthy pregnancy albeit after a chemical. Most of the immune stuff talks about the first healthy pregnancy being the trigger (or sometimes people never even have a first pregnancy).
FYI, my immune issue is thyroid. TSH also perfect. But I have thyroid antibodies, which I had to push to get tested because so many doctors stop with TSH. So not a huge deal in the vast and horrible world of autoimmune issues, but that plus a minor clotting issue seem to have caused my multiple miscarriages after an easy first pregnancy.
Do you have any autoimmune diseases in your family? My mother has lupus, grandmother had Sjogrens, so the immune diagnosis didn't come out of the blue for me even though I have always tested negative for the issues my family members have.
