Extreme Irritability and anxiety RIGHT before active labor?

Have any of you mamas suddenly developed extreme irritability anxiety and restlessness right before active labor comenced? Any thing that made you feel different? How did you labor start as well?

i have no idea but i know iv developed a nervous habbit and cant sleep at night waiting for the ball to drop

Sex got me going, but I did notice like a week prior I was getting more irritable and pissy. I labored almost 2 days and delivered on my first due date (they changed it)

I turned into raging smurfbag halloween afternoon. Started having contractions that night. Baby was born friday

Well this worries me...I have had my labor stopped three times and I make it to the safe zone in 5 days. But the past two days I have been an emotional wreck. Everything makes me mad, everything makes me cry. I seriously thought I was just being a normal pregnant woman. Now I'm worried!
