Relvay makes a pregnancy pillow. We also tell you below when you should not buy one.

The short answer

Find the one spot that feels wrong, change one thing per night, and stop after about five nights if nothing improves. Discomfort is information, not a break-in period you have to push through.

  • Keep going if one change clearly helps.
  • Stop if the same spot hurts after every change.
  • Get advice for new, sharp or spreading pain.

11:40 p.m., the new pillow on the floor

A pregnancy pillow can feel worse than regular pillows when one part of it sits at the wrong height or firmness for your body. Most of the time it is one part, not the whole pillow.

11:40 p.m.

I was 31 weeks when the big pillow arrived. Everyone said it would change my nights. On night three I pushed it off the bed and lay there on my own flat pillows, which felt like a betrayal of the money I had spent.

My neck ached by morning. The part under my bump felt like a marshmallow. I kept stacking my old pillows on top of it, so now I had the big pillow and all the old ones, and still no sleep.

  • If you wake with a stiff neck you never had before the pillow...
  • If you keep adding regular pillows on top of the pregnancy pillow...
  • If you are telling yourself it will feel better once you get used to it...

You did not buy wrong because you are fussy. A pillow built for an average body may miss yours in one specific place.

Where exactly does it feel worse?

Name the spot before you change anything. Neck, bump, hips and heat each point to a different fix, and only one of them is usually the problem.

What you noticeLikely causeOne change to try
Stiff neck in the morningThe head end is higher than your usual pillowSlide down so your own head pillow takes your head
Bump feels like it is hangingThe bump section is too soft or too far awayPull it closer, or fold a towel under it
Top hip achesThe knee section is too thin or too thickAdd or remove a folded pillow between the knees
Hard to turn overThe pillow wraps both sides of youUse only one side of it for a night
Hot and sweatyCover fabric or sheer bulk around youSwap to a lighter pillowcase or sheet over it

Ticked more than one row? Start with the one that wakes you up.

How do you run a fair test of an uncomfortable pillow?

Change one thing per night and write down what happened in the morning. Two minutes of notes beats a week of guessing.

  1. Night 0: sleep your old way and note where you ache in the morning. That is your baseline.
  2. Night 1: use the pillow exactly as shown in its instructions. No extra pillows on top.
  3. Night 2: make the one change from the table above for your loudest spot.
  4. Nights 3 and 4: keep that change, or try the next row if it clearly did nothing.
  5. Night 5: compare with night 0. Better, same, or worse than your old pillows?

  • Where did I ache when I woke up?
  • How many times did I wake to fix something?
  • Did I add any regular pillows during the night?
  • Was I too hot?
  • Better, same or worse than night 0?

If you are still adding pillows on night five, the pillow is not doing the job you bought it for.

When should you stop using the pillow?

Stop when the same spot hurts after every change, when you sleep worse than on night 0, or when any new pain appears. Five honest nights is enough to know.

There is no rule that says a pregnancy pillow needs weeks to break in. Some feel strange for a night or two because the shape is new. That is different from an ache that is still there, in the same place, every morning.

Do not push through pain. New, sharp or spreading pain, numbness or tingling is something to raise with your midwife or doctor, with or without a pillow. Hip and pelvic pain in pregnancy can need a women's health physiotherapist, not a different cushion.

Check the return window before night five. Your notes make it easy to explain why it is going back.

What changed once she found the spot?

Once you know the problem spot, the next pillow decision gets simple: keep what works, drop the part that does not.

Fiona's notes said the same thing three mornings in a row: neck. The big pillow's head end sat higher than the pillow she had used for years. On night four she slid down and put her own pillow under her head, and the neck ache was gone. The bump section still felt too soft, so she folded a hand towel under it.

She kept the setup she had built from her notes, not from the box. Dan said she had stopped sighing at 2 a.m. She said it was the first plan that had actually listened to her.

Frequently asked questions

Why is my pregnancy pillow so uncomfortable?

Usually one part of it sits at the wrong height or firmness for you, most often the head end or the section under the bump. Find that spot first, then change only that.

How long does it take to get used to a pregnancy pillow?

A new shape can feel odd for a night or two. If the same spot still aches after about five nights of small changes, it is not an adjustment period, it is a poor fit.

Should I use my regular pillow with a pregnancy pillow?

You can. Many people keep their own head pillow and use the pregnancy pillow below the shoulders, which often fixes neck ache from a head end that is too high.

Can a pregnancy pillow make back or hip pain worse?

It can feel worse if it twists you or holds a leg at the wrong height. If pain is new, sharp or getting worse, stop using it and talk to your midwife or doctor.

Is it okay to sleep without a pregnancy pillow?

Yes. The NHS suggests pillows under your bump and between your knees, and regular pillows can do that. A pregnancy pillow is optional.

If the big pillow was the problem

Relvay does not make a full-body U or C pillow, so this is not a replacement for one. If your notes said the head end or the bulk was the trouble, the closest option we sell is the 3-Piece: two small wedges for bump and back that stay below your shoulders, so your own head pillow does its usual job. If your problem was firmness between the knees, it is not a fit, because it does not go there.

Two wedges for bump and back, joined by a flat strap, about as wide as your torso. Keep a regular pillow between your knees. $79.99, 90-day returns.
