Scared I might have HIV please help..?

Hi..I made the dumb decision of having unprotected sex about a week ago. I have a slight fever, slight sore throat and am feeling really depressed over the fear that i might have hiv. I also do feel a little fatigued but no major body aches and I'll wake up with crusty eyelids. If anyone could set my fears aside please do because I feel incredibly guilty, but it has opened my eyes on how to live responsibly. I just want to move on from this and make the world a better place now.
