@Sue77 Oh Luv, I'm so very sorry to hear this latest update from you
It's no wonder you're feeling devastated, bewildered and confused about what to do or which way to go etc. I have heard that her bedside manner is a little clinical/cold for the most part which I can imagine just made you feel even worse!!
I don't understand it either and perhaps you are one of those cases where the issue can't be identified?? Are you sure you've been tested for all immune issues as that's all I can think of as to a reason for the repeated BFN's but most notably the MC's and implantation failure of chromosomally normal embryo's??
I wonder if it would be worth seeing a Reproductive Immunologist or another FS that specialises in immune issues that's close by to you to further rule in/out these kinds of issues? Despite LB saying you have no known implantation issues, it's my understanding that she doesn't believe in immune issues which is why I'm suggesting further testing in that area, not that I'm disagreeing with what her opinions are regarding the BFN's as it very well could be those issues/reasons she's outlined, but then again, it could be something that hasn't been diagnosed either??
Dr Nick Lolatgis works for the same FC LB does I'm pretty sure (Monash isn't it??) I think it would be worth going to him for a second opinion at least Luv (and it should be a smooth transition to get your files sent over to him and to transfer over to him as well) as he will probably do further testing in that area as it's my understanding he specialises in that area. I just want you to turn over every stone before you make any further decisions ok??
We're all here for you to support you and help you in any way we possibly can
P.S...You could also see "Mr Second Opinion" himself (Wazza) if you're able to travel up here????
