Its sounds very low risk to me . It sounds more like the flu to me also or mabe even a bacterial infection. Please don't obsess because once the mind starts running all kinds of things will happen that will be nerve related and seem to be ars symtoms . Keep a clear head and get testad in 3 months . You can have every symtom and in realtiy be negative so don't stay up all night on you're pc looking for symtoms or you're mind will either try to relate to what you're reading or create the symtoms youreself and belive me it doese happen .
The only way to know for sure is to get an hiv test at 3 months .
I'm sure you're fine

In good health................
