What symptoms did you have in the days/hours before labor?

K
Hey everyone! I was just wondering if any of you moms out there experienced flu like symptoms leading up to labor. I've suddenly come down with head/body aches and feeling very queasy and nauseous. I also feel very tired and sluggish and off overall but I have no fever and haven't been around anyone sick. I just don't feel like myself I guess. I've had pretty frequent BH contractions but nothing crazy painful yet. 
What, if anything, gave away that labor was about to start for you?
Thanks in advance!
