Hi gals,
Just back from the consultant, he was very helpful.
He has ordered all sorts of blood tests for Dh and I and an ultra sound.
He said he does not need to test DH's sperm as they are clearly getting to the egg but he wants to check us for chromosonal abnormalities.
He thinks the problem could be my thyroid as my TSH is at 3.9 which he said is within the normal range but in his experience needs to be at 2.5 for conception purposes. He thinks I would be a good candidate to take progesterone from 2 days past ovulation but that he wants to rule everything else out first.
I asked about progesterone extending a doomed pregnancy and he said he would by a week or 2 but not much more than that.
He was totally dimissive of the NK theory and the use of steroids. I think the jury is out on that though as so many women seem to have had success on that front.
One thing I wanted to pass on was that he mentioned 'hyper fertility' as I am getting pregnant reasonably quickly. There is a theory that in some women the uterus is 'unfussy' and allows embryos to implant outside the usual window and that this can lead to miscarriage/chemical pregnancies. He said despite the fact that many women get preggers quickly he said the normal range is 6-9 months. Just wanted to pass that on to you all!!
So we are not to try for this month as the test results can be affected by pregnancy. I will still be on here brooking no argument generally however!
cake I am 
at your DH's comments, am sure your uterus is fabulous!
