I Have Breast Cancer And My Last Chemo Was 1/17/17.

I have breast cancer and my last chemo was 1/17/17. For the last 6 days I have had diarrhea, nausea. My poop smelled like a skunk had sprayed me .(sorry) Today I went to get lab work because I was fatque, dizzy and had a fall yesterday. Thought I just need IV fluids. I did get IV fluids but my WBC shows 27,000. Given antibiotics and will go back tomorrow for more fluids. Something to worry about?
