What is the risk of getting HIV?

Hello doctor,

My name is Javier. I am 21 years old. About almost 3 months ago i had a sexual activity with a commercial sexual partner (woman). I put my condom for oral sex and also during sexual activity. I guess i did everything right since the begining. But when i finish, she stand out of me and i realized that i did not have the condom on me. I told her and she  
look on her and she had the condom on her vagina. I guess my condom slipped when she stand out of me. But i actually do not know if i made any contact. But I weared my condom during all sexual activity and that happened at the end and that is my doubt. What could be the risk of getting HIV from this experience. So since then for the last 2 and a half months I've been feeling a lot of anxiety, i mean A LOT. I vomit, i cannot sleep well. I feel very stress out and anxious about that experience. After 36 days, aprox 5 weeks later after that experience a did a HIV test which came back negative and i also did a test for sifilis gonorreha, etc. all of them came back negative and i also did a CBC test which came back everything normal. But i don't know for the last 2 and a half months i've had few common colds, sore throats, and few headaches that my doctor said it is an allergy and with a couple of lymphs nodes palpable . I dont know if this is HIV or just anxiety.

So doctor can you please tell me what can i do about this situation. Should i move on and do not need to do another hiv test? does my symptoms are because of my anxiety?. Please help me doctor . This is a very worry situation for me. and what is the risk that i have of HIV for the experience that i just described?

  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.
