Strange rash appeared and I am scared!

[worried200x]

I had unprotected sex 3 1/2 weeks ago with a female. I am circumsized.  In the first 2 weeks I had a runny nose and cough.  Now after 3 1/2 weeks I have developed a strange rash on my body.  The rash looks like small pimples, some raised with a white head some just a slight pink color.  They are random on my body and show up on my chest, nose, cheek and legs.  They are very random and never appear in large groups.  Usually they are solitary and by themselves.  On my chest I have about 10.   I have no fever or really any other symptoms or ARS other than my runny nose and cough I had.

My incident with the girl was a one time event and she claims to not have any STDs, but you never know.  Since I am still 3 weeks away from my initial 6 week test, I am simply freaking out and need some advice.

Please anyone.. HELP!!!!!

Teak,

I remember your comment, but now with this rash I am really getting more worried and the waiting is making it worse.

Does this rash sound like an ARS rash??  Please help, you are very knowledgeable.  I was becoming fine, mentally, up until now when this small rash showed up.
