Unprotected sex is a risk. It is a lower risk if it was female to male as female to male transmission is much harder.
Your symptoms are nothing like ARS, which is not mucus producing, chest congestion, runny nose, ear ache are not symptoms. ARS is not the virus it is your bodies reaction to it and the production of antibodies.
Your symptoms are nothing to do with HIV but you do need to test. If you have access to a DUO or combo you can test at 4 weeks If you don't then you test with any standard generation of HIV test at 6 weeks for a very good indication of your status and then again at 12 weeks.
The vast majority of people will develop antibodies by 22 days and a test will be positive shortly after this, if it is going to be.
Good luck.
Ars dosnt happen as quick as this, so no is the short answer. Take a test at 3 months for your results and at 4 weeks get a full std screan.
Their is also little point posting your symptoms as only a test will confirm your status. Best of luck
