Chemo or not?

Chemo day today. I've just phoned the hospital and they asked me if I was feeling ok cos I have a raised white cell count. I said I felt ok, apart from this pain I've had for a few days. She asked me all about it but said I should still go in. I'm really worried now that I won't be able to have it today. Why did it have to start going wrong at this late stage?? Not happy...
