Will I get jail time for underage drinking while on unsupervised probation?

I was recently placed on unsupervised probation for dui. I also (2 days after the dui) was charged for driving while license revoked and got 3 days jail time. Now, (about 30 days since I was sentenced for dui) I was charged with yet another underage drinking charge. This is my 3rd. I am 20 years old. Will I get jail time? How long? Is there any way to avoid it. Yes, I am a slow learner but I’m ready to change.
