hi hun.......I was dignosed as having a 36% incidence of unterine NK Cells after a biopsy, 6 times higher than normal......After 6 yrs ttc and 5 miscarriages, my 15 week old little miracle bubba is asleep here bisde me as proof it can be overcome. My regime as recommended by DR. Sacks in sydney was 25mg prednisone till week 13 and 40mg clexane injections till 20 weeks.....did the trick for us on our second cycle on this regime. Good Luck!
