Don't waste your time testing for a disease you can't have. Cold sores (which you get from someone who has that permanent virus) and cankers are unpredictable so you shouldn't try to blame them on hiv (which you don't even have) or any other disease. The first step to peace is to stop Googling hiv and the second one is to stop looking at your body trying to find problems or "hiv symptoms" that don't exist.
The only risks for HIV are having unprotected vaginal or anal sex or sharing IV drug needles. If you used a condom and it didn't break, you do not have HIV. Air and saliva inactivate the virus. You can't get HIV from anything you did.
