Anxious/antsy before labor?

Has anyone felt extrememly antsy and anxious directly before you went into labor? With out any real reason, almost as if your body just knew and was trying to warn you? I've been fine all day and now all of a sudden I just have this uncontrollable feeling that I need to get everything done RIGHT now, to the point that it's putting me in a bad mood and to the point of feeling like crying. I also feel as if my stomach is burning, idk if it's the nerves or what. This is much worse than regular "nesting" I've ever felt. Anyone else feel this way before they spontaneously went into labor?
