@miissalina I'm so sorry to read about your recent chem. I really feel for you. As I think you know, I am with the same fertility clinic as you, only a few years ago when I started they didn't believe in immune issues at all. What I will tell you (and I don't mean to sound blunt - I just wish someone had told me this earlier in my journey but I was left to figure it all out for myself - thank goodness for this forum!) is don't waste your time testing with NGF and using their luteal protocol and immune treatment. There is no comparison with the testing that Dr M does, and the protocol that he uses. Their luteal protocol saw me get my first ever BFPs but each time it ended up as a chemical. It just isn't strong enough. The steroids for example - they have you on them for 5 days. Dr M started me 3 weeks before my cycle and I wasn't weaned off until I was 27 weeks pregnant. Intralipids (ideally) are given every 4-6 weeks (depends on diagnosis and ongoing BT results). I had them pre-transfer, and then at 5, 11, 19 and 27wks. I recently saw Dr M and we discussed NGF offering infusions (200ml infused in less than an hour, where as he infuses 500ml over about 6 hours) and although he was reluctant to tell me what he really thought the message came through loud and clear. They (NGF) have no idea (or at least very little) when it comes to immune treatment. Dr M will run extensive tests, including sending blood to the USA for tests that don't even exist in Australia. I would not cycle again until you see him and all your testing is complete. If I'd followed my gut feeling on this originally I would have saved tens of thousands of $ and many tears over unsuccessful cycles.
I know of several women (from this forum and the FB group) who were told by their FS to expect to miscarry. One call to Dr M and he is in action doing everything he can to save that pregnancy, and more often than not, he is successful.
You mentioned that you have elevated ANA and high uterine NKCs. Both those things warrant an aggressive immune protocol. High dose steroids, clexane, high dose progesterone etc etc. Dr M is definitely the man to get you on the right track.
I wish you all the best for your upcoming appointment and would definitely recommend that you let Dr M run all the necessary tests before cycling again. (I saw him in mid Aug 2012 and was cycling late Sept, BFP mid Oct...so it's really not too long to wait
