The American Pregnancy Association offers these suggestions:

• Try doing exercises recommended by your doctor that help strengthen and support your lower back and abdomen.
  
  
• Don't bend over to pick something up. Squat down and reach for it instead.
  
  
• Wear comfortable, supportive shoes. Avoid high heels.
  
  
• Don't sleep on your back, get as much rest as you can, and keep your feet elevated.
  
  
• Try wearing a support belt.
