rash ulcers

Hello
I put myself in a high risk situation with a Thai prostitute in and the condom broke. I stopped immediately when she told me....Ive been worried sick about HIV
I foolishly had sex with my partner within 2 days. This was 3 weeks ago....
I now have a mark to the right of my eye resembling a rash.
Today it is more red in colour seems larger small still about half size of a quarter coin
It has been there about 10 days....
I also have a very large ulcer in my mouth, which my partner also has.
Some small pimple (but not) spots have also appeared. Red dots on my shoulder...theyve been there nearly 2 weeks  
It seems also that my body moles seem larger in size, or more....
I had other symptoms within a week of exposure that resembled a stomach problem, since dissapeared.
My partner had this also and enlarged spleen.
I read these are possible symptoms. If this is HIV can I get tested now? after  4 weeks....or is it too early....
What is the size of the rashes or skin conditions or are they non descriptive....

What you have explained is not an ARS rash. You can test at 6 weeks and if that test is negative retest at 3 months for a conclusive test result.

After 4 weeks the accuracy of the test should be around 85 %. I would advise you to start using condoms with your partner, your risk wasn't big, but there is some. Test at 6th week is 98 % conclusive and 3 months is 100 % conclusive.
