You had no risk of HIV because you can't get HIV from oral sex and if a condom fails it is a large rip apart leaving only the ring at the base of your penis and the rest of it hanging below. You are so safe that you don't even need to test.
HIV is instantly inactivated in air and also instantly in saliva which means it is effectively dead so it can't infect from oral sex. It doesn't matter if you and they were actively bleeding at the time either because the HIV is effectively dead.
Only adult risks are unprotected penetrating vaginal or anal sex or sharing needles that you inject with but you didn't do that so you had no risk. This sentence is all you need to know to protect yourself against HIV.
Even with blood, lactation cuts, rashes, burns etc air and saliva do not allow inactivated virus to infect from oral sex or from touching it outside the vagina. The above HIV science is 40 years old and very well established so nothing you can add will make your situation a risk.
You interact with others so sore throats and flu are to be expected at any time. Your symptoms are too early for ARS anyway, and are possibly just in your imagination from worry, but if concerned see your doc since it can't be HIV.
