You provide no details about your exposure except that it was "un safe", whatever that means. Irrespective, your risk of HIV is very, very low, even without testing BUT, if you are still worried about the possibility of HIV, you should get tested so you can get peace of mind.
Please get over your fear of HIV testing. Testing does not give a person HIV but it does give them the power to know what is going on and whether or not they have the infection. Most (over 99%) tests are negative and if you were so unfortunate as to have HIV, the test would allow you to seek life prolonging treatment sooner. There is no reason to delay or avoid HIV testing.
I am confident that your test will be negative. Please prove it to yourself. EWH
