Your girlfriend did not acquire HBV from you. HCV occurs from time to time in longstanding household contacts of infected persons, probably through inadvertant exposure to blood, as with toothbrushes or razors, so that's the best bet in your case (unless you have used drugs by injection, which overall is the most common source of HCV).
1) To my knowledge, HCV has no effect on HIV seroconversion.
2) You could not have transmitted HBV to your girlfriend. She got it somewhere else. But you may be at risk for catching it from her. You don't provide enough information about her test, most important whether she only has antibody showing past infection, or is positive for current infection or a carrier state (usually shown by a positive test for heptatitis B surface antigen, or HBsAg). You need to consult with your provider, or the provider who diagnosed your girlfriend, to learn whether you need to be vaccinated. Do it immediately; you don't want to mess around with the risk of catching HBV.
3) No, there is no chance you could have been infected with HBV, HCV or HIV from the exposure you describe.

"3) Can Hep B or HIv have been passed from 5 seconds of oral? I didn't notice any blood. I'm a reall mess and could use some solid answers. thanks."
No. Saliva does not contain much HiV at all read many posts in this regard, or anywhere on the net for that matter. This is one area where the consensus is the same RE: oral.
Zero risk for practical purposes as the Dr. would say.
So my test for HBV at past 7 weeks would rule me out as the cause for her infection? I don't know the exact test but she did get other confirmatory tests. Also, with the 6 weeks HIV test, there's no chance I got HIV? Thanks again.
with a 6 week hiv test, you have no worries!!
