Yes, you can sleep on your right side while pregnant, and for most pregnancies it is considered safe; the key is to avoid long stretches flat on your back in later pregnancy and to prioritize overall comfort and rest.

Can I Sleep on My Right Side While Pregnant?

Quick Scoop

  • Both the left and right side are generally safe sleep positions in pregnancy.
  • The left side is often called “ideal” because it can optimize blood flow and reduce swelling, but right-side sleep has not been shown to increase risk in healthy pregnancies.
  • The main position to avoid from around 28 weeks is lying flat on your back for long periods, because your growing uterus can press on major blood vessels and reduce blood flow.
  • If you wake up on your back or switched sides, you don’t need to panic—just roll back onto a side and get comfortable again.
  • Always follow your own doctor or midwife’s advice, especially if you have complications like high blood pressure, growth issues with baby, or multiples.

What the Medical Guidance Says

Modern pregnancy sleep advice has shifted away from rigid “left only” rules and toward a more balanced, comfort-focused approach. Research and expert reviews show:

  • Side sleeping (either side) from the third trimester onward is associated with lower stillbirth risk compared with going to sleep on your back.
  • A 2019 review found that back-sleeping carries risks in late pregnancy, but did not find a meaningful difference between left and right side sleep for most women.
  • Large maternity and sleep organizations emphasize that both left and right side positions are acceptable, with a slight theoretical edge to the left side for blood flow and swelling.

Think of it this way: the “rule” is really “sleep on your side, not flat on your back,” rather than “never lie on your right side.”

Left vs Right Side: What’s the Difference?

Here’s how the two sides are usually explained:

[3][8][1] [8][1][3] [1][8] [8][1] [3][8] [5][3][8] [1][3][8] [5][3][8][1]
Aspect Left Side Right Side
Blood flow Often called “ideal” because it helps keep pressure off the inferior vena cava (IVC), improving blood return to your heart and baby.Generally safe; may slightly increase IVC compression in theory, but studies show no clear harm in healthy pregnancies.
Organ pressure Reduces pressure on liver and kidneys; can help with swelling in hands, ankles, and feet.May put a bit more pressure on the right-sided structures, but this is usually more about comfort than proven danger.
Comfort Great for many but not all pregnant people; hip or shoulder pain can limit time on this side.Often feels more natural for some sleepers; can be easier to maintain all night with pillows.
Overall safety in pregnancy Recommended as “best option,” especially in later trimesters, but not mandatory.Considered safe; acceptable alternative if that is how you sleep better, especially when supported with pillows.

So… Is Right-Side Sleep Actually Okay?

For most pregnancies, yes:

  • Health-focused sites and hospitals state that both left and right side sleeping are safe, with the left slightly preferred but not required.
  • A popular pregnancy resource notes that right-side sleep can lightly compress the IVC but suggests using pillows to support the uterus if that’s your more comfortable side.
  • Community discussions (like pregnancy forums) are full of people reassured by their providers that “either side is fine; just stay off your back as you get bigger.”

If you roll onto your right side during the night, you are not harming your baby; in fact, uninterrupted, good-quality sleep is itself important for your health and pregnancy.

Practical Tips to Sleep More Comfortably on Your Side

You can make right- or left-side sleeping easier with a few tricks:

  1. Use a pregnancy pillow
    • Place a long pillow between your knees to align hips and reduce back strain.
 * Tuck part of it under your bump for extra belly support.
  1. Support your back
    • Put a firm pillow or rolled towel behind your back so you don’t roll flat onto it.
 * Slightly tilting your upper body backward onto that pillow still counts as side sleeping because you’re off the major vessels.
  1. Prop your upper body
    • If pure side-lying is uncomfortable, elevate your upper body about 30–45 degrees with pillows; this reduces back compression while allowing partial side or semi-reclined positions.
  1. Don’t stress mid‑night position changes
    • It’s normal to wake up on your back or the “wrong” side. Just calmly roll back to a side and go back to sleep.

When to Be Extra Cautious and Call Your Provider

Right-side sleeping is usually fine, but you should get personalized guidance promptly if you:

  • Have high blood pressure, preeclampsia, heart disease, or kidney disease.
  • Are carrying twins or higher-order multiples.
  • Have been told your baby has growth restriction or reduced blood flow on scans.
  • Feel dizzy, breathless, or suddenly unwell when lying on a particular side.

In any of these situations, your doctor or midwife may recommend favoring one side more strictly, or give you tailored positioning advice.

Mini Story: The “Left Side Only” Myth

Many pregnant people share a similar story: after hearing that left side is “best,” they start waking in the night in a panic every time they find themselves on the right. Then their midwife calmly explains that any side- sleeping is already a big win compared to lying flat on the back, and that right-side sleep is absolutely acceptable. The night after that appointment often brings the best sleep they’ve had in weeks—because the anxiety finally lets go.
