I have had fatigue and a general body ache for a week an half now, what do you think i should do?

See your doctor: Nonspecific symptoms such as you describe are associated with many types of illness, some of which require treatment. Viral illness usually get better in a week or so, but not always, and other infections like Lyme disease don't. Also there are metabolic problems that could be considered. Bottom line: you have waited long enough forthis to just get better; you need to see your doctor.
