I got a owi but my probation visits don't start for another 2 months am I considered on probation?

Yes, of course. You were placed on probation the minute the Judge said the words. If random testing (or a monitor) is part of your probation you can be pulled in at any time.

Yes of course you are "on probation" you were the minute you walked out of the court house.

So report this to the PO department
