Thanks People.
Nope, no access to DUO.
There are no test's marketed or sold to give a conclusive negative test result earlier than 3 months.
You can take a HIV DUO at 4 weeks, and its concidered 99%. Anything before that really will not confirm your status. However hard it is, try and focus on more positive thoughts. Its unlikley you got HIV from this, but only testing at the right time scale can confirm this.
...do you have access to a DUO test
