Last Sunday I began having a high fever (103), chills, and body aches. My step mother has recently had chemo and her blood platlets where removed and then replaced in Dec 2011. She has recently been receiving chemo once a month. My father is in town and I need to know if I am still contagious. Yesterday I still had a head ache but today I am just tired.

Contagious with what? Did you have the flu? A cold? I personally wouldn't take the chance of visiting without talking to her Doctor (or mine).
