Thanks ladies, DH and I have read through all your comments. It's important for him to see how much more testing etc. you have done. I booked our first appointment with a Reproductive Immunologist Dr Matthias and will speak to our FS at our follow up appointment. We are going straight into another stim cycle as the first appointment with the RI is not until the end of June. I would love our FS to try adding something to the mix but I feel stupid telling him to add Clexane etc. as I don't know what they are and if I need them. Do you ladies have any suggestion? Did any of your FS's add anything without testing whether you need it or not (no time for testing right now). I will also ask him about PGD testing but there is not point in spending the extra money until I am cleared of NK cells.
