Please read and help me

Im very scared, I had unprotected sex 3 weeks ago. Now I'm having terible headaches. I never had headaches in my life before. Can  those headaches be produced by the stress from HIV or they are symptoms of that, because on every page writes that headaches are the most usual symptom of HIV. Please help me somehow.

Thanks a lot. First of all I'm glad that you are HIV negative.
I just want to tell that my symptoms occur when I read them on net. Then I got those headaches, my bones and joint started to ache.
I will stop reading symptoms and trying to diagnose myself because I will go mad.
I will try to wait 3 months and do the test.
Btw I live in a small country with 2 000 000 people and in my town the are 21 HIV positive :S
