Whats the Main Symptoms of Hiv At Three Months And 15 Days??

I had sex with a prostitute 3 months ago. I had an HIV test and they all came back negative. My concern is a false negative, because I am an alcoholic. I was wondering if alcohol affects the test result. It is been 3 months and 15 days exactly and I have had night sweats, persistent dry cough, chronic back pain, and also red spots on my wrists. Can I be 100% certain that I have not contracted HIV? What are the main symptoms of HIV after 3 months and 15 days?

During acute HIV infection, the virus makes its way to the lymph nodes Then HIV actively replicates and releases new virus particles into the bloodstream. This usually lasts about two months. Here are the most common symptoms of AIDS. However, each individual may experience them differently and the symptoms of an HIV infection may resemble other medical conditions, like a flu-like illness within a month or two after exposure to the HIV virus, although, many people do not develop any symptoms at all. I can tell you what are the main symptoms after 3 months and 15 days, but I guess some of these are possible: lack of energy, weight loss, frequent fevers and sweats, persistent or frequent yeast infections, persistent skin rashes or flaky skin, pelvic inflammatory disease that does not respond to treatment and short-term memory loss.
