1. Why Sleeping Position Matters

After week 20 of pregnancy, sleeping flat on your back causes the heavy uterus to compress the inferior vena cava, reducing blood flow to the heart and placenta.

2. The SOS Position (Sleep On Side)

Obstetricians strongly advise sleeping on your left side. This position optimizes uterine-placental blood circulation and kidney function, helping flush waste fluids.

3. Sleep Pillows Placement Strategy

  • Place a firm pillow between knees to realign pelvic joints.
  • Wedge a body pillow under the abdomen to prevent belly sagging.
