About 5 weeks ago I had unprotected anal sex with a guy(i was the top) I met on the internet. It was my first time ever doing it and I feel like a complete idiot. I have been so scared for five weeks that I have HIV. Ive had some symptoms and I wanted to clarify. The next day I started to feel sick, my head hurt, runny nose and cough. it went away after a couple of days so I thought it was a cold. I asked the guy if he was HIV negative and he said he was but for some reason I really dont believe him. So I kept bothering him and asking him to tell me the truth and he said he didnt and i still kept bothering him so he stopped responding. So after 2 weeks, I went and got a blood test done for all STDs and it came out negative, cause of the window period. They told me that with the blood test itll show up after 2 to four weeks so I went yesterday at the 5 week mark. After two weeks though I started getting more symptoms, muscle aches, sore throat, a little bit of coughing but not really a fever. I also had a loss of apetite and diarreha. I also have had chest pain and shortness of breath for the past 2 weeks. Thats the only one that has actually stayed. I have been so scared and nervous that I have HIv. all of these symptoms come and go but most dont come around the same time, is that possible? today I noticed I started getting a little bit of shaky hands, and i dont know if thats a symptom either. I dont know if this is stress of if this is ARS, please help :(
