First of all, I would not put a lot of faith in a visual assessment.
When was the exposure? Was it oral only? What kind of test did you have done?
I'm also not sure why you would start taking antivirals without a positive test and for "small red dots" that aren't bothering you.
Based on what you posted, there isn't anything "risky" about your exposure.
If the antiviral made them disappear does that mean I have them?
