My Story On Subbing, What Do You Think

So. I had an interview and quit smoking for about 2 weeks. I didn't hear back so I started smoking again. Four months later I get a job offer. I accepted and put in my two week notice. I had two weeks to get clean or practice subbing. Since I'm fat and smoke 4-5 bowls daily there was no way I could get clean in two weeks.
So I start practicing subbing. I put my own urine into two small sample listerine bottles. They were .9 oz each. I temp'd right away and it was 97.1 degrees. I wrapped each bottle in a paper towel and tucked one under each breast (my boobs are very large). I kept them under there for 6 hours and checked the temp. They were at 94 degrees. I tried this a couple times, same result.

So today was my first day/orientation/drug test. I collected my clean sample from my son (don't judge) this am at 6:30. Poured it into my bottles and tucked them in. I started orientation at 9, drug test was at 11:30. I checked the temp on the way and both bottles registered at 94. I wrapped tie warmers around the bottles and tucked them back in. I arrived at the clinic, they were 97 degrees. I waited inside for about 10 min, I told them I had been holding for a while, so they rushed me back. She handed me a cup with a temp strip on it, no directions on how full. I sat and peed into the toilet while opening the two bottles and pouring the urine into the sample cup. I put the bottles back in my bra and walked out. She checked my urine, temp was 94. And after a short discussion on sea world I was done and samples were off. They are doing a 10 panel screen.

I know my sample was clean, so is there any reason I should doubt that I passed? I'm worried about the fact that the urine was held at a higher temp for 6 or so hours and the fact that i used a opposite sex urine sample.
