1. you knew your license was revoked
2. you were driving

You can make excuses for breaking the law, but you knew it was wrong and decided to do it anyway. Then you did not report it right away, but I assume you are going to wait till the next day ( or longer ?)
Only he knows what he will do when you call him.
