To obtain a conclusive negative result you will need to test out to three months.
Sounds like you had a bacterial infection, not HIV. Your negative test result shows that you don't have HIV. I don't see any need for further testing, it's up to you to test again at a later timepoint if you're still anxious.
This is not the correct page for posting to the doctors 20011978 @ $15.00 a pop, this is the page to hear opinions from civilians like myself and others who weight in on your post and freely give you our advice and support. I'm sure you already know that unprotected sex is already risk and i would advise a test for hiv @ three months after your encounter. Symptoms are not a good rule of thumb as it varies from person to person-the way the body reacts, ect. I don't know the background of your partner so it's hard to give you further advice but if you wish state if your partner was a csw-commercial sex worker -or- ....? Good luck to you and feel free to add any other information to your post you think may help...
