Thanks for your reply! My concern is that I actually wasn't concerned at all about having contracted HIV. I only started to think about it on that tuesday when I started researching my symptoms and they matched ARS. Have there been ARS cases that have surfaced at 4-5 days? If so do the symptoms always occur simultaneously?
4 days after exposure is way too soon to be experiencing ARS symptoms. They come on around 2-4 weeks after exposure- never within mere days. I GUARANTEE you that the majority of your symptoms are due to stress and anxiety over your situation. Being excessively anxious about something causes headaches, fatigue, upset stomach, nausea, night sweats, waking up during the night, weight loss, loss of appetite- you name it and anxiety brings it on!
You did have unprotected sex so yes, this is considered a risk. However, a one-time unprotected vaginal sexual encounter is about a 1 in 2,000 chance of HIV transmission for the male. Most one-time encounters do NOT result in infection- but of course they can, although this is very rare. For a white, heterosexual, non-IV drug using woman- the stats that she would have HIV is 1 in 1,000 and more likely around 1 in 10,000 according to the doctors on the expert forum here. Your chances are very low, as are the chances she had HIV to begin with.
To know your status, test at 3 months after the last exposure. Testing at 6-8 weeks will give you a very good indication of your status.
Your symptoms are not ARS- not even close. It's way too soon and I assure you that your anxiety is causing them. Try to relax and take this all in stride. I wish you the best of luck.
