It is normal for people to be worried when they develop flu like symptoms (e.g. fever, rash, sore throat) after they have a sexual encounter they are concerned about. Many people will think the worse. I usually remind people that flu like symptoms are common and can be caused by many different conditions like the common cold. Just treat the symptoms as a reminder you are concerned about what happened and it would be good to go for a HIV test.
HIV cannot be diagnosed by any combination of symptoms because all these symptoms can be caused by many different conditions. The only way to find out if you have HIV is by having a HIV test.
I would recommend going to see a health care professional and describing your symptoms to them. You could also ask them to do a HIV test for you.
Some people can get embarrassed asking their family doctor for a HIV test. If this is the case for you I would recommend visiting an STI clinic or another clinic. Have a look at our clinic finder for a clinic in your area.
