Doesn't matter. You didn't have a risk and don't need to test.
HIV is ONLY transmitted by:
1) Having unprotected (no condom) penetrative anal or vaginal sex, OR
2) Sharing IV drug equipment with other IV drug users.
It’s really as simple as that. HIV can also be passed from an infected mother to an unborn child, or to a newborn through breastfeeding.
I was not aware Oraquick developed a product as sensitive as you said.
Taking this from your post how effective it is, a 4 week negative is encouraging.
However, if she has hiv, ( chances are she doesn't) transmission female to male is not easy even if you penetrated her. Still don't see a risk.
What you describe isn't a risk for HIV and doesn't warrant testing.
