So I took a pre-employment drug test today...

Okay. I need some help. I'm not a heavy user, I usually only smoke a few hits every night and that's if I can afford to find some(I can usually make a gram last over a week. ) I got a call for a drug screen a couple weeks ago, but I rescheduled because I was out of town. I smoked every day when I was on vacation, and the day we got back(Sunday)my wife bought me a pack of AVO and told me that it would help me pass my test. She said that shes done it to pass a drug test 3 times, and the online research I did helped persuade me more into doing it. So the first night I took 2, and drank two huge cups of water. The next morning I woke up, pissed caution sign orange, took 2 more and gulped down more water. Every time I went to the bathroom, I drank another cup of water. I took two more before I went to bed, woke up this morning and took 4 of them and chugged water all day until I felt like I was going to puke. I took my test and waited for my results. The lady said I had a faint line on thc(the line meaning you got a negative result) and that she would have to send it to the lab to confirm that I have no thc in my urine. With that being said, my question is this.. How ducked am I? What should I expect? I've done more research and read that AVO will give a false positive at regular doctors office, but when a lab reviews it that they won't find any trace of tjc(something about some chemical that bonds itself with thc and disguises it). Has anyone gone through this same problem?!
