I had non-protected sex with this girl about 4 months ago. I was inside of her a total of about 2 minutes, and pulled out and ejaculated. About 4-5 weeks later, i developed a chronic cough that lasted about a month. I also had swollen glands in my neck. I was so stressed out thinking about it, to the point where i made myself sick. I didn't have a fever, or any rashes. I actually went to the doctor, and he tested me for Mono, which was negative. I had sweaty palms and feet, but i think that was just from the high levels of stress and anxiety. I asked her if she was ever tested for HIV, and she said she was in the past, which was negative. I noticed the other day that she had a red rash on her wrist. Hypothetically, if she was positive, is there a 100% chance i have HIV?
