Mucus plug/ Labor question.

Emily
I  was doing some reading about the mucus plug because I'm at the stage where I could lose mine whenever now. This will be my second child. But I read that if it's your first time giving birth and you lose it labor could still be weeks away whereas if you've had a child before and you lose your mucus plug then it said you're more than likely going into labor within a few hours is that true ?
