This thread will probably be closed as per the terms of service we cannot offer medical advice. If you were exposed to body fluid at work you should seek medical advice and follow the exposure plan/ policies of your employer.
Since you mentioned you are anxious about exposure in general here is some general info for you. The main concern with body fluid exposure is bloodborne pathogens like HIV, hep B, hep C. Per OSHA and the CDC you are at risk for transmission of these pathogens if your bloodstream, via broken skin or mucous membranes, is exposed to blood or certain body fluid. Per OSHA bloodborne pathogens can be transmitted by blood or "semen, vaginal secretions, cerebrospinal fluid, synovial fluid, pleural fluid, pericardial fluid, peritoneal fluid, amniotic fluid, saliva in dental procedures, any body fluid that is visibly contaminated with blood, and all body fluids in situations where it is difficult or impossible to differentiate between body fluids".
If a health care worker is exposed to the above most workplaces have policies that center around detecting and trying to prevent transmission of bloodborne pathogens. This often includes testing the source (person the fluid came from) and/or the exposed person at the time of exposure and sometimes in the future. In some situations the employee may be offered prophylactic drugs for a period of time to try to prevent them from contacting certain diseases (usually HIV).
Now aside from pathogen exposure there are certainly other problems that can happen in the workplace- an employee who is exposed to urine from a pt who has recently had certain chemo meds or radioactive treatment may need followup for that, or someone might be sprayed with corrosive fluid, etc. In general most people would say when in doubt report it and seek medical advice.
