A 6.47 isn't likely to be a false positive, but you can certainly retest.
It's not from your recent encounters, either. It takes time for antibodies to develop - at minimum, 2 weeks, and up to 12 weeks.
I've seen reports of higher results come back as false positives, but those are definitely the exceptions, not the norm.
At 12 weeks post exposure, you can get a Western Blot test, either from your doctor or from Terri Warren - https://westoverheights.com/getting-a-herpes-western-blot/
Herpes doesn't cause testicular pain. That's something else. Work with your doctor to find the cause of that.
