Shaytan always tries to mess up with those who have love of Allah swt in their heart. So please ignore the doubts totally and act upon the certainty. Therefore if you are not sure that your wodhu broke or not you can carry on your worship and say no nothing came out. Even if you feel some kind of movement or feeling of wind in the passing of the wind area. Because many times due to the area being sensitive many have complained certain sensation or hair movements or feeling of leaking wind and so on. All such must be ignored.
