38 1/2 weeks and have been having contractions on and off for 24 hrs. Once they get a pattern for me to time, they stop. I have GD and will be attempting a VBAC as long as I go into labor on my own.and my baby does not grow too big. Today ive tried sex, hot bath, shaking my booty to some hip hop, eat a pregnancy pizza, and now drinking raspberry leaf tea with cinnamon sticks. Any ladies know how long it takes for labor to start if any of these techniques work?
