Yes, and I believe it is needed to be done mid cycle. I also believe that TTC that cycle would not be advised. The procedure is not painful and is done in the clinic - Dr S has a pathologist who works with him & counts the NK cells personally - so it's a fairly time exhaustive procedure. NK cells are there for all of us - just when there is an over abundance is it a problem.

You will be given some fairly strict instuctions if I know Dr S . Sometimes the meds have to be commenced prior to pregnancy or at least during the luteal phase of your cycle each month.

If I may add. If NK cells is the issue the ivf pgd process will not avoid miscarriage. So, it is important that you rule the NK cell issue out. NK cells basically fight off the pregnancy so it doesn't differentiate on how the pregnancy was conceived iykwim???

You also mentioned that one of your babies was female and that the docs questioned the validity of the test???

So you may understand a little more. When a currettage is done and the baby is female it cannot be clear weather the chromosomal material came from the mother or the baby so therefore a chromosomal defect cannot be completely ruled out. It is possible that the chromosomes were yours and not your babies. I hoep that makes sense.?
