Egg Urine test for therapy?

My situation is court mandated I had to get evaluated and they decided to put me I. A group therapy program that is unrelated to drugs and alcohol. I did get arrested for drinking a while back and this is my last step before court dismisses the case. Although in the class drugs and alcohol are brought up, it’s majorly about seeking safety, ptsd, etc. I had a horrible ex boyfriend who was abusive during the time of me getting in trouble with the law. I’m a first time offender so they offered me this program to get it cleared off my record. I was never told by the judge or any court employee that I was on probation or couldn’t drink. This therapy class I’m in my therapist told everyone if we’re court mandated we have to give 2 urine samples a month. As we all know it was recently Thanksgiving. I did drink with family, and it was my dad’s birthday Tuesday so he drove us to dinner and we had some cocktails. I’m a small girl high metabolism. I went to my class this week she told me to take my first urine test by tomorrow (Friday) I have been freaking out ever since. I’ve drank nothing but water to try and hydrate up. I am worried I won’t pass because I’ve been told it can take up to 80 hours. Some people have told me if it’s over 30 hours I should be fine. I am just confused on what will happen if I do test positive, being that I am not on probation and was never told I have to abstain from drinking. I know that’s the smartest thing to do right now but with the holiday season it’s a little hard, I like to enjoy myself. If anyone has been through something similar please let me know your thoughts
