Frequency of tests

Hi all,
Im quite nervous, next week i have my regular 2 month appt at hosp and will have my white count checked as normal, however i haven't had another BMB since my diagnosis in January. They tried one in July sed the Marrow taken was not viable, not enough i think to do the test properly and sed my next one would be a molecular blood test which they have waited to do in Dec, well here it comes. Shouldn't it be done more frequently, i am really anxious, wanting to know if the glivec has worked or not. How often should it be done, is it every year or every six months...What about FISH testing as well, with everyone talking about the frequency of their testing im beginning to feel I am falling between the cracks, obviously im going to have to ask for frequent testing, should i have to? what if they say NO?? Sorry about the rambling!
