Okay, so you had vaginal sex, so your infection (if you had one) would only be genital. Your eye and scalp symptoms and your all-over body itch wouldn't be related to this at all.
You don't mention when your genital symptoms started in relation to your encounter.
Mucous and post nasal drip, etc., wouldn't be related to herpes. If you still have that, follow up with your doctor. Perhaps you have allergies (you can develop them at any time.) Maybe it's something else, but it's not herpes.
In any case, your herpes test at 8 weeks is a good indication that you do not have herpes, but to be definitely sure, test again at 12 weeks. You don't need a vzv test for this encounter, just a type specific IgG blood test for herpes.
