Dubya and his cronies are cutting off funds to states that have anonymous testing sites. That's why such sites are getting harder to locate. Cases like yours are prime examples of how this policy is going to discourage people from getting tested.
That aside, I would say your risk is negligible to nonexistent and I do not feel testing is warranted.
Good luck on your upcoming nuptials! (And remember to vote the current rightwing politicians out of office in November!)
