@WishingWaiting also, I was a little sceptical of Is Your Body Baby Friendly. I felt it used a lot of emotive quotes and miracle case studies which felt a little manipulative in places. It seemed like a hard-sell, whereas Lesley Regan's book was gently empathetic but mostly stuck to the facts.
I just don't have the clinical skills (obviously!) to differentiate between the science of the two approaches. They both seem adamant on their view points, which each make sense, the way they explain them. Yet they disagree on so much. How are we supposed to discern which is more valid?
It's so hard when you are willing to do whatever it takes, but you don't know where to put your trust.
Alan Beer points out that the NHS only diagnose a cause in 50% of recurrent miscarriage investigations, and says it is not acceptable to just write the other half off as unexplained. He believes most of these people have immunological issues (which is Dr Shetata's approach, as I understand it).
However Lesley Regan says many of these immunological treatments have no clinical validity, and suspects that most of the success stories are just women who would eventually have had a successful pregnancy anyway. Her view is more to keep on trying and play the numbers game.
On Dr Shehata's website (CRP) it says only 3-5% of miscarriages are caused by anatomical issues, 6% from blood disorders, 20% from hormonal causes and 60% from immunological disorders. I don't know where these numbers are from, but the NHS seems to focus mainly on anatomical, blood and hormonal disorders. Which would of course give an incomplete picture, if Dr Shehata's data is correct.
It's interesting that you say Raj Rai has identified immunological issues in your case though, so he (and the school of thought at St Mary's) are not against this completely.
It seems to be the theory around NK cells that is controversial. From what I've read on here, almost everyone who consults Dr Shehata is told they have a problem with their NK cells, and then put on quite an elaborate treatment protocol, for each cycle, from ovulation - not just upon conception. So you can imagine this can quickly become a very draining and expensive treadmill of treatment that is hard to get off.
I think I will try Raj Rai first and hope he identifies - or eliminates - some of the basics first.
