I ve never been concerned with HIV before but I heard someone mention it and tell me it was easy to get and ever since I ve been freaking out. I ve been feeling but a few months ago I remember experiencing very bad headaches and I don t remember running a fever but I always took Tylenol to help the headache and I d always sweat very badly as if I did have a fever that was breaking. It last for a few weeks and I blamed it on my contacts which I had changed three weeks later and haven t experienced anything else like that, prior to that I had unprotected sex twice with a guy who I don t know could be infected. I was wondering if maybe that was my first phase of HIV, I m a 22 year old female.
