You can't get HIV when you used a condom, and micro holes are a myth so unless it failed you had zero risk. If a condom fails it is a large rip down the seam and it hangs in tatters so that didn't happen.
I don't know why you don't accept the advice of 2 doctors, but you need to.
Only a doctor can diagnose your rash , and rash don’t come alone it must be present with high fever und swollen lymph nodes ( don’t try to check if your lymph nodes are swollen because if you touch them all the time the lymph nodes are going to get swollen ).
Don’t listen to Lolita , the 3 month window period is old news and the 6 month window period is a myth. Get tested now, a 4th generation test will rule out any infection anytime now , get tested .
