Fever, fatigue and sweaty are common symptoms that can be caused by many different things.
There are no symptoms that are caused by just having HIV. The symptoms people get with a HIV seroconversion illness are common symptoms that can be caused by many different conditions, for example 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 test.
Glad that you went to see a doctor, they can give you information on what tests to get and if there is any need for a follow up test.
It is great that you used a condom as that really reduces your chance of having an STI pass to you. Have a look at our “Know your chances” web page, it provides information on your chances of getting or passing an STI depending on how you are having sex.
