Most experts recommend sleeping on your side during pregnancy, ideally on your left side, especially from the second half of pregnancy onward.

Best side to sleep on when pregnant

  • Left-side sleeping is usually considered the ā€œgold standardā€ because it helps keep pressure off a major vein (the inferior vena cava), which supports better blood flow to your heart, uterus, and baby.
  • This position also helps your kidneys work more efficiently, which can reduce swelling in your legs, ankles, and hands.

Is right side sleeping okay?

  • Sleeping on either side (left or right) is generally safe, and many guidelines say it doesnā€™t clearly matter which side as long as you are on your side and comfortable.
  • If you strongly prefer your right side, using pillows to slightly tilt your belly and hips can ease pressure on the big blood vessels and keep circulation flowing well.

Positions to avoid (especially later on)

  • In late pregnancy (around 28 weeks and beyond), regularly going to sleep flat on your back is linked to reduced blood flow and has been associated in research with higher stillbirth risk, so it is usually discouraged as a main sleep position.
  • Stomach sleeping is generally fine early on, but as your bump grows it usually becomes too uncomfortable, so side sleeping becomes the default.

Practical comfort tips

  • Use pillows: between your knees, under your belly, and behind your back to support your hips and lower back in a semi-fetal position.
  • Donā€™t panic if you wake up on your back; simply roll back onto a side and get comfortable again, as what matters most is the position you settle to sleep in most of the time.

Quick Scoop (SEO-style)

  • Main keyword: which side should you sleep on pregnant ā€“ answer: left side is preferred, but any side is okay as long as you avoid long stretches flat on your back in late pregnancy.
  • Current ā€œforum discussionā€ and ā€œtrending topicā€ angle: Many pregnant users online share that strict left-only rules stress them out; newer guidance emphasizes ā€œany side, not backā€ to balance safety with realistic, less anxious sleep habits.

Always check with your own midwife or doctor, especially if you have high blood pressure, growth concerns, twins, or other complications.
