I knew because I had a uncontrollable trickle of fluid every time I moved or my baby moved and also sometimes just randomly. It actually happened while I was on the toilet and in my half alseep stupor I thought I just couldn't stop peeing. LOL!
Depends. If you think it did then it's best to get checked. Are you having contractions? Leaking fluid?
