Help!

My now 3 year old has been potty trained for almost a year. A couple weeks ago we moved and she started peeing herself, not just a night but she could be wide awake and she would just pee. I asumed it was just because we moved and didn't really yell at her. It's been quite a few weeks now and she is still doing it and I just don't know how to make her understand that it isn't good. I just don't know what to do anymore.
