Will I P a Drug Test?

Ok so i smoked a little on the 22nd, I then smoked a little more on the 25th, and then on the 27th i had a brownie. I have a probation test on the 12. Before smoking i was perfectly clean and i have been chugging water. Do you think i will be fine/ And don't give me the "Don't use drugs" BS cuz i don't wana hear it.
