If I violated my probation and have a court date for next month, will I go to jail?

With any probation violation there is a possibility the judge will send you to jail, the question to ask is "how serious is the violation". If you picked up a new criminnal offense, or did something aggregious in your violation, then judges are more inclined to request jail time. If the violation is less serious, then the judge could either impose further restrictions or extend your probation as a result.
