Answer: 

Hi there, and thanks a lot for contacting the AIDS Vancouver Helpline for your HIV/AIDS related health information. It seems you're concerned about the possibility of HIV transmitting during an encounter. We're happy to answer your question for you.

Protected sex, as this was, is considered a low risk activity. This means that while transmissions are possible, they require specific circumstances (like the condom breaking). It sounds like your condom may have been a little loose, but that it did not fail. It being a little loose does not increase the risk of transmission. For more information on proper condom use, check out one of our favourite resources at SmartSex.

We at AIDS Vancouver recommend routine HIV testing for all sexually active individuals, so it's great you were proactive and went for testing.

Here is a bit more information on the tests you've had:

Test Name
Method
Window Period
Conditions
Enzyme Immunoassay Antibody (EIA) 3rd Generation (ELISA) Blood test that looks for antibodies. Up to 95% of infections are detectable within 4-6 weeks post exposure. Most people develop detectable antibodies in 21-25 days. Most commonly available testing method. Conclusive at 3 months post exposure.
NAAT (PCR RNA & DNA) Nucleic-Acid Amplification Testing (NAAT) extracts and amplifies the genetic material of HIV and tests for it with a Polymerase Chain Reaction (PCR) test. NAAT tests generally take two forms: DNA PCR and RNA PCR tests. 2-3 weeks post exposure DNA PCR NAAT tests are usually used for screening babies of HIV+ mothers. RNA PCR NAAT tests are often used to screen blood or organ donations. Both measure the viral load of a positive person’s blood. Conclusive at 3 months post exposure.

You'll see that both tests are considered conclusive, meaning their results are taken as accurate, 3 months (or 12 weeks) post exposure. Remember the risks associated with your encounter, but both tests were done too soon to demonstrate your present status conclusively after this encounter. If you'd like to know your status conclusively, you'll have to go for another test after 12 weeks.

Thanks a lot for contacting the AIDS Vancouver Helpline with your question, we hope it has been answered fully.
