How to Use Pregnancy Pillows to Support Pelvic Floor Health
Supporting your pelvic floor during pregnancy is key to preventing pressure, pain, and long-term complications. The right pregnancy pillow can help you maintain posture, reduce strain, and protect your core — all while you sleep or rest.

I didn’t understand the importance of pelvic floor health until I was in my second trimester and started feeling pressure in my lower abdomen. A friend told me that it wasn’t just about Kegels — how I sleep, sit, and rest all impact that area too. That’s when I started using my pregnancy pillow not just for comfort, but for support where it really mattered.
Most people associate pregnancy pillows with belly or back support, but if you’re intentional, you can use them to take pressure off your pelvic floor — especially in the later stages of pregnancy. Let me show you how I used mine to make a noticeable difference.
Why Pelvic Floor Support Matters During Pregnancy
Your pelvic floor muscles hold up your bladder, uterus, and bowel. As your baby grows, those muscles carry more weight — and without proper support, they can weaken. That’s what leads to issues like leakage, pelvic pain, or prolapse after birth.
Using a proper sleeping position with a pregnancy pillow helps keep your hips aligned and weight evenly distributed, which reduces strain on those deep core muscles.
How I Used My U-Shaped Pillow for Pelvic Support
With a U-shaped pregnancy pillow like this one on Amazon, I’d sleep on my side with one arm of the pillow between my knees and the other behind my back. That alignment kept my hips level and reduced downward pressure.
I also placed a small rolled towel between the pillow and my pubic bone when I felt extra pressure. That little adjustment changed everything.
C-Shaped Pillow Setup for Better Pelvic Floor Alignment
If you’re working with a C-shaped pillow like this one, curve it around your body with the bottom part between your thighs and knees. This position keeps your pelvis neutral, especially if you’re prone to tucking your hips under when you sleep.
I’d also prop one side slightly higher using a folded blanket underneath the pillow to tilt my pelvis gently forward — reducing strain in my groin and tailbone.
Support While Sitting or Resting During the Day
Pelvic floor pressure isn’t just a nighttime issue. During the day, I sat on the couch with my pregnancy pillow curved behind my lower back and wrapping around to support under my thighs. That gentle lift off the seat took weight off my perineum and made sitting for long periods more manageable.
You can also place your pillow like a donut and sit in the center during high-pressure days. This donut setup using a U-shape pillow worked great for me when everything felt heavy.
Using Pregnancy Pillows for Better Side-Lying Posture
Sleeping on your side is recommended during pregnancy, especially on the left. But without proper support, your hips collapse inward, pulling your pelvis out of alignment and putting extra tension on your pelvic floor.
Using a full-body pregnancy pillow like this ergonomic one on Amazon between your knees and ankles helps keep your spine and pelvis aligned, reducing the risk of strain.
Why This Matters for Postpartum Recovery Too
The better you support your pelvic floor during pregnancy, the easier your recovery will be after delivery. I noticed less pressure, fewer aches, and faster healing — and I credit the way I used my pregnancy pillow just as much as my exercises.
Even now, I use the same pillow to sit, breastfeed, and rest in positions that protect my core muscles.
I realized early on that if I didn’t support my pelvis properly while lying down, I’d wake up with soreness in my lower belly and groin area. That’s when I started experimenting with how to angle my pregnancy pillow. I found that slight elevation of my hips using the bottom arm of a U-shaped pillow reduced that pressure dramatically.
I also learned to avoid crossing my legs, even slightly, while sleeping. It threw off my alignment and added uneven pressure. That’s why I kept a firm pillow section between my knees and ankles at all times — which my full-length body pillow like this one made super easy.
During my third trimester, pelvic heaviness became more constant — not just at night. I began placing the C-shaped pregnancy pillow behind my back while sitting and letting the long curve extend under my thighs. That lightened the load on my perineal area and made long sitting sessions tolerable.
If you’re dealing with symptoms like vulvar swelling or pelvic heaviness, consider using a pillow to slightly raise your hips when lying down. I folded a blanket under my pregnancy pillow’s hip section to create a gentle incline. It improved circulation and took pressure off my pelvic floor almost instantly.
Sometimes I even used my pillow while lying on my back — which I know isn’t always recommended during pregnancy — but with proper elevation, it became a helpful position. I placed a wedge or folded towel under my upper back and used the U-pillow under my knees to take pressure off my lower abdomen.
I also used my pillow while doing pelvic tilts and breathing exercises. I’d lie on my side, place the pillow behind my back, and do gentle inhales and exhales while focusing on releasing tension in my core. That small change helped me stay consistent with my routine.
On days when walking became uncomfortable, I’d recline on the couch with the pregnancy pillow wrapped under my knees and behind my lower back. That supported my tailbone and kept my pelvic floor muscles relaxed instead of overworked from constant tension.
Using your pregnancy pillow postpartum is just as important. I used mine during recovery to sit more comfortably and avoid putting pressure on tender areas. This extra-soft U-shaped pillow gave me the perfect cushion for both back support and pelvic relief.
If you’ve been diagnosed with pelvic girdle pain (PGP), don’t skip pillow support. I adjusted mine to align both legs evenly and keep my pelvis stable at night. That simple fix made a big difference and helped me avoid sharp pain when standing up in the morning.
I avoided sitting flat on hard surfaces without support. Even at the dining table, I brought my pillow to sit on or wrap behind my back. Just that extra cushion kept my weight more evenly distributed and made everyday tasks less exhausting on my core muscles.
One of my favorite tricks was using my pregnancy pillow as a wall brace. I’d lean against it with my feet on a stool and do deep breathing exercises that activated my deep pelvic floor support muscles without strain.
Lastly, don’t wait until symptoms show up. I started using my pillow proactively in the second trimester, and I truly believe it helped prevent a lot of issues other moms experienced. It’s not just about comfort — the right positioning using your pregnancy pillow is part of real, everyday pelvic floor care.
