Hi, this saturday night i had a one night stand with this girl, i did use a condom however i remember at one point that it came of after realizing this i puled out and did not ejaculate in to her however i was unprotected for a short while. Since then i have started to feel really ill like the flu. Yesterday (monday) i was not to bad just felt under the weather, however today i have had a really bad headache and some pain in my testicles. After doing some research on the internet i came across many different articles how this is the effect of HIV but i also read this only starts to happen after 3 months or so. So am i just over exaggerating and making my self even more ill or can the signs of HIV start immediately. I am a 19 year old male who is straight however i do not no much information about the girl she was a friend of a friend and she seemed fine. ow and also i have started getting some pains in my upper abdominals but it feels more like my stomach than my abs. Please could you help me i am really scared
