Got my biopsy and Chicago blood results yesterday. Looks like my CD56 are in the uterine lining and are prolific. My only option is aggressive IVIG therapy. My question is has anyone else had this recently and how was it? Any side effects of IVIG?? Also, how many sessions did you have. I conceive naturally so will not be factoring in any IVF treatment - not sure if that will make any difference - I doubt it! Many thanks everyone!
