Clean for over a year in past 10 days smoked 6 times..PLEASE HELP!!!!

I was clean for over a year. Since Thursday APril 28th I have smoked 6 times over the course of 10 days. I know I would test positive right now. I know that metabloism has alot to do with it, however, what time frame am I actually looking at? When will I be "LAB" safe? I have a family court matter and a court date tomorrow. I believe they will not whip out a cup and say "here piss in it", however if one was requested by the end of the week, I'd be in big trouble. I do not know when or where the test will be given. I just want a clear understanding of how long I can expect to stay pos for. Thanks so much.. please reply if you have any info.......... Thanks:-(
