Hello, I'm so sorry for the position you are in.
I lost my first 5 pgs - 4 mc's and 1 late loss.
There are no words for how shit it is, are there?
I also went to tommy's recurrent miscarriage clinic, after initially being treated at a shit local hospital.
I found that there really isn't a general consensus about treatment which makes it confusing and crazy making to try and decide what to do.
Some look on thyroid testing/ nk cells etc as the 'new' treatments that are just being incorporated into the system and some consultants are sniffy about them as they are pushing the boundaries of their knowledge, others think some of these new treatments are snake oil salesmen selling false hope...it is so difficult to know who to believe.
With regard to nutrients, one consultant told me it was vital I started to address any deficiencies in my diet as it might make all the difference and then another told me to carry on if it was making me feel better but all I was doing was making my urine more expensive.
I just wanted to lock them all in a room for 48 hours so they could come to some kind of agreed protocol for treatment that I could then follow.
The one thing that really jumps out of your post is the fact that the third baby was tested and no problems were found. Most miscarriages are the result of genetic problems (at least 80%) and so I think that would make me more inclined to explore the thyroid/nk etc side of things as potentially that embryo has what it needs to make it but then something is going wrong, it isn't an abnormal embryo that is never going to be viable. Does that make sense?
You can pay a set amount and get all your notes photocopied and sent to you, so might be worth contacting tommys for this. You would then know all your results for thyroid etc and might save money too if you are going elsewhere as they could take a view on which tests need to be repeated and which don't.
