Protected sex is not a risk, unprotected sex would warrant testing. I am not saying that you had a high risk to worry about, there are 2 factors that deems you at low risk :
A. Low HIV infected demographics.
B. In a 'female to male' transmission scenario, it is observed that for the male to contract this virus from a single act of unprotected vaginal exposure is difficult, i.e. it usually takes multiple exposures with an infected female for a male to contract the virus.
HIV is not diagnosed with help of symptoms. Also, your symptoms seems unspecific to HIV since it is very generic to any other ailment that could occur in your day to day life.
It's advisable to stay calm, get a test at 28 days from the date of your last unprotected vaginal / anal intercourse with a IV Generation HIV test. It's most likely to provide you with a negative result, take it and move on.
Always use condoms consistently and correctly to keep worries of HIV away.
