The risk of HIV is extremely low from these encounters, regardless of the HIV status of your partners.
The symptoms that you are describing are consistent with a viral
syndrome..including ARS. Fever is typically present in ARS, though.
Hepatitis C is difficult to transmit sexually, Hepatitis B can be transmitted sexually, including through oral sex.
However, hepatitis B would not cause many of the symptoms you are describing....it can cause pain in the right upper abdomen, jaundice, nausea/vomiting or no symptoms at all.
As you know, the only way to know if you have seroconverted is to be tested. Your chance of HIV is about 0.04% from one oral sex encounter--therefore it is highly unlikely that you have HIV.
I know that this can cause extreme stress and worry given the multiple symptoms. I believe it is more likely that you developed cold (sinus congestion/sore throat) that led to swollen glands as well. Canker sores are common and do not indicate HIV. The rash could be viral/non-HIV as well..or acne as you originally thought.
