Thank you Doctor,
To set the provide the previous missing information, out sexual lifestyles are more or less alike, few partners and almost always protected. My final test was a 4th generation 8 months post experience and we are both from southwestern Virgina. Although I do not believe that changes any of your recommendations. Thank you so very much and I certainly am thankful for your help.

You don't say enough about either your or your partner's sexual lifestyles, but I have the impression both of you have been at pretty low risk for HIV. That said, one week after her last sexual exposure is too soon to be 100% confident she doesn't have HIV, although that time is conclusive for the most common STDs, gonorrhea and chlamydia. And you don't say when you were last tested and how long that was after your last unprotected sexual contact. But as careful as you apparently have been, I imagine you have been at very low risk, if any, for HIV and most STDs.
To your specific questions:
1) As noted above, you don't provide enough information for a definitive reply, but I doubt there was any risk at all for HIV or any of the common STDs.
2) Well under 1 in 1,000 such women have HIV -- and in most parts of the country, it's a lot lower than that. But you can't safely apply such broad statistics to any single partner. From the scant information you have provided, and knowing your partner had a negative HIV test about 6 months ago (even if only a week after her last sexual contact), I would guess the chance she has HIV to be under 1 in a million, probably zero.
3) PEP??? Are you kidding??? Of course not. If I were in your situation and your partner's, I wouldn't insist on either of you even being tested for HIV.
