HIV Symptoms. Tired from last 5 days.

Please take time to read the mail and request you to kindly respond to the mail. I had a unprotected sex with my friend who is married and she claims that she dont have HIV and also have healthy life, it happened 17 days back and it happened twice, before that i have physical relation with three other girls and three of them don't have HIV, from last6 days i have been experiencing light body pains(shoulder, hands and below knees) but these are not severe and not present all the day, also head ache some times and neck pain, eyes are burning, little body temperature not all the time and dry cough which is not very much and also not continuous. Out fear i googled the symptoms and all are these are present & in google it says 2-4 weeks the symptoms will come out and also you said only with HIV infected person if we have sex we are at risk. Note: I was on fasting from last 35 days and eat only one time a day also i am feeling bit tired from last 5 days.
