I am a straight 21 year old male. I had unprotected sex for the first time on June 25 with a girl for a few minutes. I started with a condom but could not finish so I took it off for the end. A few days after, I developed a lot of pain in my groin area and legs. I went to my doctor and he said I have an infection and prescribed me penicillin. It turned out to be a muscle strain after an MRI and pain pills. However, I finished the medicine. About 7 days into the medicine treatment, I developed a rash on my chest, oral thrush and a rapid heart rate. My doctor said I was allergic to penicillin and gave a steroid which helped for a while. It then came back and I have had severe anxiety about it being HIV. I asked my partner to get tested about 7 weeks later and she did and was negative. She said I have nothing to worry about however my anxiety is killing me. I did an Oraquick test at 11 at 11 weeks. I still cannot get it out of my head. Should I be worried? I have never felt so alone and scared in my life. Thank you.
