I got divorced in 2011. I have made some very poor choices since then. I am a 32 year old female. I was told that hiv can lie dormant for 5 to 10 years without showing up on a test. My most recent unprotected intercourse was 4 weeks ago. 6 days after that encounter I got the flu. I went to the doctor and she did a flu test and said she wasn't sure if it was positive or not. I am very concerned. Can hiv lie dormant for years without a person knowing? When do I need to test? Do flu symptoms happen that soon after exposure? I had body aches, fever of 99.5, cough, fatigue.
