No risk. Using condom correctly for vaginal or anal intercourse protects against transmission of HIV. Testing was not needed.
Protected sex is safe sex from HIV. This is good news you used a condom! Keep doing that and you will be safe. The only ways adults get HIV is from unprotected vaginal or anal sex with penetration or sharing IV drug needles. So, no risk at all and no reason to test again. However, for future reference, the cmia duo test is only accurate at 28 days and beyond. You would not get a positive on that test unless you had an exposure before the one you describe here as this one is no risk at all.
