Welcome to the forum. Thanks for your question, the core of which is "What do you think the chance of being infected with HIV from this incident?" The answer is that there is almost no chance you caught HIV from these events.
Why not? Most of your assumptions are wrong. Although HIV has been common in Thailand, that's no longer the case. That country has seen one of the most effective HIV prevention programs in the world. Second, it is statistcially unlikely your partner had HIV, and you can safely assume she isn't infected. Third, even with entirely unprotected sex, HIV is rarely transmitted during any single heterosexual exposure. Fourth, you had entirely protected sex. Fifth, your symptoms are not at all suggstive of a new HIV infection, which doesn't cause nasal congestion or other "sinus" symptoms.
Since you're nervous about it, I recommend you have an HIV test. Negative test results typically are more reassuring than anything an expert can say based on probilities and statistics. Enough time (4 weeks) has passed for 100% reliable testing with the duo ("4th generation") tests for both HIV antibody and p24 antigen; or you can wait until the 6 week mark for definitive results by the stand-alone HIV antibody tests. Even thought most official advice is for testing at 3 months after the last exposure, in fact these tests are virtually 100% reliable by 4 weeks or 6 weeks, respectively.
Feel free to return with a comment to let me know the result after you are tested. In the meantime, stay mellow. It is virtually certain you didn't catch HIV. If I were in your situation, I wouldn't even be tested and I would be continuing unprotected sex with my wife. This really isn't the sort of exposure you need to be worried about.
