Ok. Yes during ARS, early hiv infection can resemble mono. There are other symptoms as well. For example, I knew someone who was Hiv infected early that only had one symptom; an really bad headache for a week. The doc said he was just newly infected. Early symptoms due resemble sore throat, usually high fever, Extreme fatigue, maybe bowel changes, etc.
Now with that being said, most people with these symptoms do not have HIV. You said you had a negative test 7months after unprotected activity. You DO NOT HAVE HIV. 7month will show whether you have HIV. 3months will show if you have HIV.
Now unless you have had unprotected sex since your last test, than I wouldnt be worried. Even if you did, that does not mean that you have HIV. Mono is mono. You were diagnosed with Mono. Get it. Just cause you are diagnosed with mono surely does not indicate you have HIV. Having mono and having mono symptoms are different. You were diagnosed with something based on your symptoms. That was mono. Nothing to do with HIV. K. I know I may sound redundant but Im trying to make sure you understand. Your fine sweety and believe me I have the same fears.
