will I pass a lab drug test

I took a urine drug screen on 12/31 and tested positive for thc but haven't smoked in 2 months. They sent me to a lab on 1/2 . I took rescue detox ice, pissed a lot. Went to the lab and they had to observe me so I couldnt give them my mid stream because they put something in the toilet to catch all of my pee. I came home and took a home drug test and it was negative. Today is the 10th and I still haven't heard from my employer. Do u think I passed or should I be worried. I dont wanna call them because I dont wanna look guilty. Somebody help!
