Find a good chiropractor who adjusts pregnant moms and babies. Made a HUGE difference to me. I even got adjusted IN labor and all of the pain that was in my low back was instantly gone. I've had 3 babies at home without any pain meds, so keeping my pelvis moving and decreasing my pain was a HUGE. One of my babies was even over 10 pounds and no tearing, etc.
