NKC went up after treatment???

[chelsharmony]

can any of you help out here - i was tests and NKcells came up at 27 and then the next week at 21 then went on prednazone 10mg once a day for about a month now and tested again at 41!!! How is that even possible??? Im so upset and sad right now. I was going to start the IVIg treatment with IVF which i was gonna start in 2 days but now cant cuz the number went up. He wants me off the steroids, which made me feel great btw, and to see a specialist, Dr Kwak-Kim. He says we need to get this under control or at least know what the heck is going on b4 wasting time and money on yet another IVF round.
I have had 4 m/c in the last 2.5 years all at about 6 weeks. 2 fresh rounds of IVF, several rounds of clomid and femara and 4 IUI's with injectables. 3 out of the 4 pregnancies were "off" months where it was just no meds and my hubby and i at home BDing. I ovulate on my own every month and i am 35 y/o. I have 2 children that are 13 and 11 and never had an issue conceiving or keeping the pregnancy with them.
I just dont understand how the **** things could go up - has this ever happened to anyone?????
