You have been told it is conclusive. Which means there is no need for further test. If you want more test, go ahead.
You used a condom and it didn't break, therefore you had no risk. Condom protected sex is not "low" risk, it's NO risk. Symptoms are never used to diagnose HIV, but since you used a condom and it didn't break then your symptoms are not HIV.
So you used condoms during sex. What sex did you do? Yes anal sex is risky. But since you used condom, low risk.
Hiv symptoms dont appear so soon. As for yours symptoms, they sound quite distressing and could potentially be an std. I recommend go see a doctor and get and evaluation.
