Pelvic Girdle Pain at 12 Weeks Pregnant

Pelvic girdle pain (PGP) is a collection of conditions causing pain in the pelvic joints — including symphysis pubis dysfunction (SPD). It affects up to 20% of pregnant women and can range from mild discomfort to severe disability.

👶 What's Happening at Week 12

Your baby is now the size of a plum.

  • All organs and structures are formed — the rest of pregnancy is growth and maturation.
  • Reflexes develop: the fetus can open and close fingers, curl toes, and make sucking motions.
  • The kidneys begin producing urine.

🔬 Why You're Experiencing Pelvic Girdle Pain at Week 12

  • Relaxin hormone loosens pelvic ligaments more than necessary, causing instability
  • Asymmetrical movement or loading of the sacroiliac and pubic symphysis joints
  • Pelvic floor muscle weakness or imbalance
  • Previous pelvic injury or trauma
  • Prior pregnancy with PGP increases risk of recurrence

💊 Relief Tips for Week 12

1
Pelvic PhysiotherapyA pelvic floor physiotherapist is the most effective treatment provider — manual therapy, exercises, and joint-specific techniques provide significant relief.
2
Pelvic Support Belt (SI Belt)A sacroiliac belt worn around the hips (not the belly) compresses and stabilizes the pelvic joints.
3
Move SymmetricallyKeep knees together when turning over in bed, getting in and out of cars, and getting dressed. Avoid asymmetrical movements that load one side of the pelvis.
4
Avoid Aggravating ActivitiesAvoid stairs where possible, avoid breaststroke swimming, avoid heavy lifting, and minimize prolonged walking or standing.
5
Crutches (Severe Cases)In severe cases, crutches can reduce pelvic loading. Discuss with your physiotherapist.

⚠️ Call Your Doctor If…

  • PGP is so severe you cannot walk or bear weight
  • You hear or feel a clicking or grinding at the front of your pelvis (pubic symphysis)
  • Pain extends into the thighs or is accompanied by leg weakness
  • Pain after delivery is not improving within 6–8 weeks postpartum

Frequently Asked Questions

What is the difference between PGP and SPD?

Pelvic girdle pain (PGP) is an umbrella term for pain involving any pelvic joint (sacroiliac joints, pubic symphysis). SPD (symphysis pubis dysfunction) is pain specifically at the pubic symphysis — the joint at the front of the pelvis.

Will PGP affect my birth options?

Most women with PGP can have a vaginal birth. Your physiotherapist and midwife/OB will work with you on positions that minimize pelvic strain during labor. Having an epidural is generally safe.

Does pelvic girdle pain mean something is wrong with my baby?

No — PGP is entirely a maternal condition affecting the pelvic joints. It has no effect on the baby.

Can PGP be prevented?

There is no guaranteed prevention, but maintaining pelvic floor strength before pregnancy and avoiding asymmetrical movements reduces risk and severity.
