I am on supervised probation as well and yes you are watched while you pee. They dont directly watch the pee leave your body but escort you to the bathroom and stand behind you a few feet away. You need to go drug test yourself right away and if you dont pass then try to use the dilution method.

How do you know he is going to test you in 2 days? If you look respectable when you go in for your monthly report and do exactly what he/she says then you will most likely not get tested a lot if at all.
