very mild sore throat , could this be a hiv symptom ?

Hello and welcome to e health forum. ‎

HIV is diagnosed based on the detection of HIV antigens and antibodies in the blood samples, and not based on ‎the ‎‎‎‎‎signs and symptoms that you may be having. ‎

One of the main problems in relying on HIV symptoms themselves is that they are notoriously vague and almost ‎all ‎‎‎‎‎the symptoms may in fact be symptoms of a different disease. ‎

HIV is transmitted only by having multiple sexual encounters with a HIV positive person, and not with a single ‎sexual ‎‎‎encounter. The risk of HIV transmission by a single sexual intercourse is about 0.04%, which is very less. In ‎your case ‎‎since you did use protection, it is more likely that you may be HIV free.

Most likely your symptoms appear to be due to bacterial or viral pharyngitis, which is common when you have new sexual contacts. It could also be a presentation of your stress and feeling of guilt. You can take ‎‎‎Advil or Motrin, to reduce your symptoms which may be very helpful. ‎

In case, of persisting doubts and anxiety, you can do a 4th generation HIV test after 4 weeks of exposure. This test if negative, will ‎confirm your HIV negative status.‎
