Driving on a Suspended License after DUI in Orange County,CA?

3 years ago I got charged with DUI and driving without a license. I went in front of a judge, paid all my fines, took the classes and learned my lesson. I still however don’t have a driver’s license and hadn’t been driving but a month ago I had to drive 3 nights and was pulled over one of them. My DUI probation wasn’t up until august this year so they impounded my car and gave me a citation for driving under a suspended license and I have to appear in court next week (to the window, clerk? in front of a judge?) What are the chances of me being put in jail? I don’t have money for an attorney so what can I do? can I go to the court without one or is that too risky?
