You have posted on the wrong site. Questions about HIV belong on the HIV prevention site. I will do my best to answer your questions with this reply but, if you have additional questions or follow-up they must be on the HIV Prevention site. Sorry
Even if you had not use a condom and IF she had HIV (this is unlikely, most commercial sex workers do not have HIV), your risk of getting HIV would still be only 1 infection per 1000 exposures. In your case, you used a condom during your exposure to this partner but the condom came off as you withdrew from her vagina. As a result, your sex was protected and there is virtually no risk to your form this exposure. You negative HIV test 36 days following your exposure confirms this. At 7 weeks the HIV test would be expected to detect well over 95% of infections acquired 7 weeks before. Thus when you consider your condom protected sex, your low risk of getting infected and your negative HIV test, you can be confident that you did not get HIV. You do not need to be concerned and you do not need further testing.
It sounds as though your anxiety could be the4 cause of many of your other symptoms. They are not due to HIV.
This ends my response. As stated above, there will not be additional answers on this site. Further questions about HIV should be on the HIV site. EWH.
