Only way to know if you have HIV is to be tested after three months of last exposure. You may find free HIV testing centers who do rapid tests by doing a google search online with your city. If you have trouble email me and I will help you find a center near you.
symptom chasing is pointless so ignore them when trying to diagnose HIV as the only way to do so is via a test. Test at 3 months post your last unpotected encounter to obtain a conclusive result, i suggest you stop worrying honestly, your partner may not have even had hiv and the symptoms you are experiencing is simply a result of your anxiety, take it easy and let us know how you get on!
