Your biggest problem is not HIV but drunkeness. Check on your drinking please because that seems to impair your judgement. As for de exposure,it is next to zero but please try to avoid Oral sex especially if u r not sure of any open wounds in your mouth. Nevertheless,you should be ok from this one.
You can relax. Oral sex is risk free; HIV has never been known to be transmitted, at least not from oral to penis.
Does UD mean your partner's viral load is undetectable? If so, he isn't infectious at all; you wouldn't catch it even with unprotected anal sex, and for sure not by oral.
And the fingerstick blood tests are pretty much all 3rd generation tests, which are nearly by 6 weeks -- and if your symptoms were due to HIV, the blood test would be positive. Test results always overrule both exposure and symptoms, you can be very certain you don't have HIV.
1) These aren't typical ARS symptoms. You have a cold.
2) Discolored tongue isn't thrush. Minor viral infections can cause coated or dark tongue, so it's probably just from your cold.
3) It's hard to judge whether one's own lymph nodes are inflamed. But even if they are, your blood test result indicates HIV isn't the cause.
So there are many reasons for you not to be confident you didn't catch HIV. Your final blood test will also be negative. You can take it to the bank!
