I lost my plug about three days ago and I've been having some lower back pain and slight menstral like cramping. The cramping is low in my pelvic region. Are these just early signs of labor? Should I call my doctor? I'm not due until Jan. 12th, and I am full term so I'm not that worried. I would like to have my baby before the new year, so it could also be wishful thinking. Any opinions?!
