Some swelling of the feet is normal during pregnancy—especially for women who must stand all day.
What to do to prevent it:
Put your feet up as often as you can during the day.
When resting, lie on your left side.
If your feet are very swollen, or they are swollen already when you wake up in the morning, or your hands and face also swell, these are signs of danger during pregnancy. See a health worker or go to a hospital.
