> In the third trimester, Symphysis Pubis Dysfunction (SPD) discomfort often peaks as your baby descends, making specific movements like turning in bed or walking more challenging.

Experiencing pubic bone pain in your third trimester can be quite common, and for many, it's when Symphysis Pubis Dysfunction (SPD) truly makes its presence known. This discomfort, sometimes called 'pubic-bone pelvic pain,' stems from the softening and increased mobility of the joints in your pelvis, particularly the symphysis pubis at the front.

## Why it shows up this trimester

As you move into your third trimester, your body is preparing for birth. The hormone relaxin continues to soften ligaments, and your growing baby is getting heavier. A significant factor in this window is when your baby's head begins to 'drop' or engage into your pelvis. This shifting weight and pressure can put additional strain on your already softened pubic joint, intensifying the sensations of SPD. Your center of gravity also continues to shift, which can alter your gait and posture, contributing to the discomfort.

## What it tends to feel like now

In the third trimester, SPD often manifests as a sharp, shooting, or grinding pain directly over your pubic bone. You might also feel it radiating into your groin, inner thighs, or even your lower back. Activities that require single-leg weight-bearing, like stepping up, getting dressed, or turning over in bed, can become particularly challenging and trigger flare-ups. Getting in and out of a car, or even walking for extended periods, might feel more difficult than before. It's a sensation that can leave you feeling less confident in your movements.

## What helps in this window

Finding gentle ways to support your body can make a significant difference. One option might be to explore a pelvic support belt, which can offer external stability to your pelvis. Gentle, symmetrical movements like pelvic tilts, cat-cow stretches, or swimming can help maintain mobility without overstraining the joint. Many parents find relief by keeping their knees together when getting in and out of the car, turning in bed, or getting dressed. Resting when your body signals it's time can also be incredibly helpful. Warm baths or a warm compress on the area can provide some ease.

## Working with your care team

It's always a good idea to discuss any persistent pain with your OB or midwife. They can help rule out other causes and offer personalized guidance. They might suggest a referral to a pelvic floor physical therapist or a chiropractor who specializes in prenatal care. These professionals can offer specific exercises, manual therapy, and strategies to help manage your SPD. Remember, your provider is your best resource for your specific situation, and collaborating with them ensures you're making informed decisions about your comfort and care.
