So we had our wtf mtg with the RE on Fri (the 13th no less too) and genetic testing on our fetus was completely normal. A healthy little embryo! They said there could be a rare instance with some chromosomes moving (not sure I fully understood) but RE didn't think that was the cause. I feel that SCH may have caused things; RE thinks it was the blood clotting disorder. RE did put out there some schools of thought (not done at UCSF tho) believe immunological reasons could influence this. We only have 2 embies left; love this donor and freaked that my environment failed. My thoughts are to see what I can get tested (like in Walkinlab) to see if any merit? RE gave us a Dr in NY to consult with but feeling if I can get some blood work done to see if this has any merit that I would start there. Tests that I have researched, I have listed below:
- Antinuclear antibodies (I can do this at Walkinlab)
- Natural Killer cells (trying to find this at Walkin; is it under another name? Or other route here?)
- Antiphospholid antibodies (did the full workup after MCs, had many done and tested postive for blood clotting disorder. Was on Lovenox and baby aspirin this last DE IVF and still MCd)
- Thyroid - did test this and currently on 50mg Levo; numbers were ok before this last DE IVF
- Others? What else should I test or ask about immunological?
DH and RE want to move forward with the same plan as it did work to get us a BFP. I feel the same but want to make sure I have covered every base. I was devastated yesterday by this news. Our betas were strong and I new this was a strong baby, my body failed 
We also found out baby was a little boy; I pretty much lost it at that point. Thanks for any advice. Still hopeful just scared.
