May I please offer you lovely ladies some advice:

I have watched my sister go through IVF for 6 years now and nothing to show for it. She has been anywhere from 4 weeks pregnant up to 10 weeks and lost it.
If it wasn’t for my endless search of the Belly Belly forums over the last 8 months and the wonderful ladies who put all this information on here, I worked out what might be my sister’s problem.
I got my sister to do the NK cell test back in Aug 2009 and now after all these years she now has an answer to her problem – NK Cell Antibodies.

Please ladies go and get tested for it, its just a blood test. You can also do the test when your doing a cycle which is great.
Just one thing to remember make sure your 100% healthy when you do the test.
(You can’t have the flu or anything else. Make sure your not on antibiotics when doing the test, cause it can affect the results, as I have found out and have to redo the test)

I know they do it at St George Public Hospital at Kogarah Sydney NSW.
The test you need to ask for is: Flow Cytometry for NK Cells.

If I can save just one lady from the heart ache that my sister has been through - it has been worth it.
