Symphysis Pubis Dysfunction in Pregnancy: What Actually Helps

Symphysis pubis dysfunction — SPD, sometimes called pregnancy-related pelvic girdle pain — is the sharp, grinding, or aching pain at the front of the pelvis that shows up when the joint where your two pubic bones meet gets irritated. It is common, it is not a sign that something is wrong with your baby, and there is genuinely useful Pilates work you can do around it once you understand what tends to provoke it and what tends to calm it down.

What Symphysis Pubis Dysfunction Actually Is

The symphysis pubis is a small, mostly-fixed joint at the front of your pelvis. During pregnancy, the hormone relaxin loosens the ligaments around your pelvic joints in preparation for birth, and for some people that joint ends up moving more than it is used to, or moving unevenly on one side versus the other. According to Physiopedia, roughly half of pregnant women experience some form of pelvic girdle pain, about a quarter describe it as severe, and it most often starts around week 18, peaks between roughly weeks 24 and 36, and usually settles within about three months of giving birth. Pain is typically felt right at the pubic bone and can radiate into the groin or inner thigh, and it tends to flare with walking, stairs, getting out of the car, or rolling over in bed.

I want to say plainly: relaxin is not the whole story. Research has not pinned down a direct causal link between relaxin levels and who ends up with pain, so this is not simply a hormone problem you have to wait out. It is also a load and coordination problem, which is exactly where Pilates has something to offer.

Why This Shows Up During Pregnancy

As your uterus grows, your center of gravity shifts forward, and your body compensates with changes like an increased curve in your lower back. That shift changes how load travels through your pelvis. Add joint laxity on top of that, and the deep stabilizing muscles around your pelvis and hips — the ones that normally share load evenly between the two sides — can start working less efficiently. Physiopedia notes that risk goes up if you have had low back or pelvic pain before, if you have had a pelvic injury, if your work is physically demanding, or if this isn't your first pregnancy. None of that is something you did wrong. It is just useful to know, because it points straight at what helps: restoring even, coordinated loading rather than just resting and hoping.

Movements That Tend to Make It Worse

The clearest pattern across the research and clinical sources I read is that asymmetric, single-leg loading is what tends to provoke SPD pain. Physiopedia specifically flags single-leg stance activities like climbing stairs as a common pain trigger, and MamasteFit makes the same point about single-leg movements such as walking, stairs, and lunging becoming more painful once pelvic stability is compromised.

In a Pilates class or home session, that translates to a short list of things I'd modify or skip for now:

• Standing single-leg work, including single-leg circles or kicks without support
• Wide straddle stretches or deep hip abduction, like a full split-stance or extreme side-lying leg lifts
• Twisting combined with weight shifted onto one leg, such as stepping and rotating in the same movement
• Getting on and off equipment by swinging one leg over — step up and turn instead, keeping your knees together as you pivot
• Long, unsupported single-leg balance holds, even in a gentle standing series

None of this means lying still. It means keeping your legs working together, close to the midline, and supported, rather than far apart or independently loaded.

Pilates Moves I'd Reach for First

The exercise approaches with the best support, per Physiopedia, are individualized programs that build motor control and strength through the abdominal, spinal, pelvic, and pelvic floor muscles together, alongside manual therapy, support belts, and education on daily positioning. WebMD adds a practical, low-provocation list built around pelvic floor activation, gentle stabilizing breathwork, and stretching, which lines up closely with how I'd sequence a session:

• Pelvic floor and deep core connection — slow pelvic floor squeezes paired with a gentle 360-degree breath, done seated or side-lying, several times a day rather than as one long set
• Supported bridging — small pelvic tilts and low bridges with a pillow between your knees, which keeps both sides of the pelvis loading evenly
• Side-lying leg work kept close to the midline — small clam-shell style lifts with knees bent and stacked, not full straight-leg abduction
• Seated inner-thigh and hip stretches — gentle, short-hold stretches rather than deep, sustained ones, which WebMD lists among its core recommendations
• Step-downs and staggered-stance work, progressed slowly — MamasteFit's research points to short-range, supported single-leg stability drills, like a shallow step-down holding a rail, as a way to rebuild the coordination that reduces pain, once symptoms allow it

The through-line is symmetry and support first, range and challenge second. If a movement narrows your stride or keeps your knees roughly in line with your hips, it is usually a safer starting point than one that spreads your legs wide or puts weight through one side alone.

The rule I give people is simple: if it makes the pubic bone itself sharper or more tender, that's your body telling you to regress the movement, not push through it.

Everyday Habits That Matter as Much as Exercise

SPD is provoked by ordinary daily movement as often as by exercise, so a few habit changes tend to do as much good as any specific move:

• Keep your knees together when getting in and out of a car — sit first, then swing both legs as a unit
• Take stairs one at a time, leading with the less painful leg, and use the rail
• Avoid standing on one leg to dress or step into pants; sit down instead
• When rolling over in bed, keep your knees together and log-roll as a unit rather than twisting
• Physiopedia's clinical guidance also points to a pelvic support belt as something that can meaningfully reduce pain for some people, and to getting individualized coaching on lifting mechanics and positioning for daily tasks, including things like sex and housework, rather than guessing at what's safe

These small changes reduce the number of provoking moments in your day, which matters more than any single exercise.

Where to Start: The Honest Verdict

If you're dealing with SPD, Pilates is genuinely one of the better tools available — the research consistently favors individualized, symmetry-focused stability work over rest alone. But "Pilates helps" doesn't mean any Pilates class helps. A general mat class full of standing single-leg series and wide-leg stretches can make things worse. What helps is a short daily practice built around pelvic floor connection, supported bridging, midline-focused leg work, and the daily habit changes above.

Start small: five to ten minutes of breath and pelvic floor work, plus supported bridging, most days. If pain is limiting your walking, sleep, or basic daily tasks, or isn't easing with these changes, that's your cue to see a pelvic health physiotherapist rather than trying to modify your way through it alone — and as with any pregnancy exercise question, check with your midwife, OB, or physiotherapist before starting something new, especially if you have other pregnancy complications.

Frequently asked

Is symphysis pubis dysfunction dangerous for my baby?

No. SPD is a musculoskeletal issue with the pelvic joints, not a sign of a problem with your pregnancy or your baby. It's painful and limiting, but it isn't a medical danger sign on its own.

Will SPD go away after I give birth?

For most people, yes. Research summarized by Physiopedia shows pelvic girdle pain typically eases within about three months postpartum as ligament laxity resolves and normal movement patterns return. A pelvic health physiotherapist can help if it lingers.

Can I still go to a regular Pilates class, or only do exercises at home?

A studio class can work if your instructor is willing to swap out standing single-leg series and wide-leg stretches for the midline-focused, supported versions described here. If they can't modify on the spot, a shorter home practice is the safer default.

Should I wear a pelvic support belt?

It's worth trying. Clinical guidance summarized by Physiopedia lists support belts as a legitimate option for reducing pain alongside exercise, though how much they help varies person to person, so check with your midwife or physiotherapist about fit and timing.
