My HIV poz gf who is a drug user injected her blood into me after getting me drunk. Her viral load has been undetectable for years. 2 weeks after the encounter, I was down with fever for a day, coughing and sore throat for another 2 weeks, fatigue and feeling generally uncomfortable. However, I did not notice any swollen lymph nodes nor rashes on my body. Could I have been infected from the incident even with her undetectable viral load?
