That was food for thought for me and my gut says to err on the side of caution and have an IVIG infusion prior to ovulation if trying to conceive naturally as the miscarriages are too hard on me, especially on my thyroid which takes several months to stabilise post miscarriage.
Like you, I am a firm believer that IVIG works as my last pregnancy with IVIG was the longest and HCG doubled and even tripled following the infusions.
Dr Matthias also recommended Neupogen injections on a positive pregnancy test. What was his explanation for this? You say it's because of the multiple miscarriages???
Prior to undergoing another stimulated IVF cycle, I have to wait until March 2014 for the appropriate PGD testing to be introduced to my IVF clinic as the current testing does not detect polyploidy. Hence, trying to conceive naturally in the interim...
I have asked Dr Matthias to call me to discuss. Will let you know if/when I hear from him...
I wish you all the very best on your journey.
Please keep in touch.
