CBC results after chemo for AML M2 patient

Hello,
Patient was diagnosed with AML M2 few weeks back, and has been hospitalized.
Started chemo (7 /3 regiment) and currently not receiving any chemo, as doc is doing blood tests every now then to check for wbc and platelets count.
now, the wbc was 0.2 and then 0.4 till it reached 1.1, and then yesterday started decreasing, now it's 0.7. and so are the platelets.
I need to know if this is an indication of any sort, that maybe the drugs did not work, or that the blasts are returning, thus the low count of white cells, can you please answer urgently?
Also i need to know another thing. The doctor asked for some cytogenetic tests (fish inv 16 and (8:22) ) , and she was negative on both, does this indicate that she is in the infavourable or intermediate prognosis, or has no indication?
