Im leaking pee to the point where i have to wear a pad 38 weeks pregnant?

I am leaking pee and im not aware of it until i go to the bathroom, so i have to wear a pad. I know this is embarrassing but i really want to know if this means i am close to labor, i know i can go at any time and im getting anxious. But i have a lot of the braxton hix and there is soo much pressure down there sometimes its hard for me to walk. But my question is did any one else have this problem, and if so how long was it before they went into labor?
