It's very common to notice new twinges, aches or pressure around your pelvis as pregnancy progresses. Your growing bump, stretching ligaments and a baby that's shifting position all put pressure on this area, and for most people it's an uncomfortable but harmless part of pregnancy.
Because 'pelvic pain' can describe many different sensations — sharp twinges, a dull ache, or pressure low down — it helps to know what's typical and what needs checking. This guide covers the common causes, when pelvic pain is expected, self-care that helps, and the signs that mean you should contact your doctor or midwife.
What is pelvic pain in pregnancy?
Pelvic pain in pregnancy covers a range of aches, pulls and pressure sensations felt in your lower abdomen, hips, groin or across your pubic bone. It's extremely common, particularly in the second and third trimesters, as your growing baby, stretching ligaments and shifting joints all add pressure to the area.
For many people it's a normal — if uncomfortable — part of pregnancy that comes and goes and responds to rest and gentle self-care. In some cases, ongoing pelvic pain centred on the pubic joint and hips is a specific condition called pelvic girdle pain, which can benefit from dedicated physiotherapy. Occasionally pelvic pain is a sign of something needing medical attention, particularly if it is severe, one-sided or accompanied by other symptoms.
Different from pelvic girdle pain
If your pain is specifically around the front of your pubic bone or radiates into both hips, and worsens with walking, stairs or turning in bed, it may be pelvic girdle pain — see our dedicated guide for targeted advice.
What causes pelvic pain in pregnancy?
A combination of normal pregnancy changes can cause pelvic aching and discomfort.
Stretching round ligaments
The ligaments that support your uterus stretch as your bump grows, which can cause sharp or aching pulls in your lower abdomen and groin.
The hormone relaxin
Relaxin loosens the ligaments and joints of your pelvis in preparation for birth, which can make the whole area feel less stable and more prone to aching.
Your baby's position and weight
As your baby grows and moves lower into your pelvis, especially in the third trimester, this puts direct pressure on your pelvic floor, bladder and joints.
Braxton Hicks contractions
These 'practice' tightenings can sometimes be felt as pelvic pressure or period-like cramping and are usually harmless.
Constipation and bowel changes
Pregnancy can slow digestion, and a full bowel or trapped wind can add to pelvic discomfort.
More common if…
- You've had pelvic pain in a previous pregnancy
- You're carrying twins or more
- You have a physically demanding job or lifestyle
- You have a history of pelvic joint problems
When pelvic pain is normal
Mild, intermittent pelvic discomfort is a normal part of later pregnancy for most people. These are usually reassuring:
- Occasional sharp twinges or pulls, especially when you change position quickly, cough or sneeze.
- A dull ache or pressure low in your pelvis that eases with rest.
- Discomfort that comes and goes without a regular pattern and settles within minutes.
- Mild period-like cramping without bleeding, especially with occasional Braxton Hicks tightenings.
| Usually normal pelvic pain | Needs medical attention | |
|---|---|---|
| Onset | Gradual, linked to movement or position | Sudden, severe, or one-sided |
| Other symptoms | None — you feel otherwise well | Bleeding, fever, dizziness or shoulder-tip pain |
| Pattern | Comes and goes, settles with rest | Regular tightening or cramping before 37 weeks |
Twinges are usually just stretching
Quick, sharp twinges when you move suddenly are almost always round ligament pain — normal stretching, not a sign of harm to your baby.
Warning signs — get medical help now
Occasionally pelvic pain needs urgent assessment. Contact your doctor or midwife urgently, or go to your nearest emergency department, if you have:
Seek urgent medical care if you have
- Severe, persistent or one-sided pelvic pain, particularly in early-to-mid pregnancy — this needs to be checked to rule out serious causes such as an ectopic pregnancy.
- Pelvic pain together with vaginal bleeding.
- Pain with a fever, chills, or feeling generally unwell.
- Pain with dizziness, fainting, or pain at the tip of your shoulder.
- Regular tightening or cramping pain before 37 weeks that doesn't settle with rest.
- Severe pain that stops you walking or carrying out normal activities.
If your baby's movements feel reduced or different, contact your maternity unit the same day.
Sudden severe or one-sided pain needs urgent review
Sudden, severe, one-sided pelvic pain — especially with dizziness, shoulder-tip pain or bleeding — always needs prompt medical assessment, whatever stage of pregnancy you're at.
Self-care & home remedies
Most pregnancy pelvic pain can be eased with simple, safe measures.
Rest & positioning
- Rest with your feet up and avoid standing for long periods.
- Sleep with a pillow between your knees and one supporting your bump.
- Move slowly and avoid sudden twisting or standing up quickly.
Gentle movement
- Gentle walking and pregnancy-safe stretching can ease stiffness without straining your pelvis.
- A warm bath or shower can relax tense muscles.
- Ask about a prenatal yoga class geared towards pelvic comfort.
Support & comfort
- A pregnancy support belt can take some pressure off your pelvis for some people — ask your midwife or physiotherapist.
- A warm compress on the achy area can ease muscle tension.
- Wear flat, supportive shoes to reduce strain through your pelvis and lower back.
Keep your bowels moving
Constipation can add to pelvic pressure. Drink plenty of water, eat fibre-rich foods, and stay as active as you comfortably can — ask your midwife about safe options if you're struggling.
When to consult a doctor
Book a non-urgent appointment with your doctor or midwife if:
- Pelvic pain is persistent, worsening, or affecting your ability to walk or sleep.
- Home measures aren't helping after trying them for a week or two.
- You're unsure whether what you're feeling is normal stretching or something more.
- You have pain alongside urinary symptoms, such as needing to wee more urgently or discomfort passing urine.
- You'd like advice on a support belt or a referral to physiotherapy.

Open the Pregnancy TrackerFrequently asked questions
Is pelvic pain normal in pregnancy?
Yes, mild to moderate pelvic pain is very common, especially from the second trimester as your bump grows and your ligaments stretch. It's usually harmless, but severe, one-sided or feverish pain should always be checked.
What does round ligament pain feel like compared to other pelvic pain?
Round ligament pain is typically a sharp, brief pull or ache in your lower tummy or groin, often triggered by sudden movement, coughing or standing up quickly. Other pelvic pain tends to be a more general ache or pressure that isn't linked to a specific movement.
Could pelvic pain mean early labour?
It can. Regular, rhythmic tightening or cramping pain before 37 weeks — especially if it doesn't ease with rest — can be a sign of preterm labour, so contact your midwife if you notice this pattern.
Is it safe to exercise with pelvic pain?
Gentle, pregnancy-safe activity is usually fine and can help, but stop any exercise that increases your pain and speak to your midwife or a physiotherapist for tailored advice.
When should I go to hospital for pelvic pain?
Seek urgent care for sudden, severe or one-sided pain, pain with bleeding, fever, dizziness or shoulder-tip pain, or regular tightening before 37 weeks. These need prompt assessment.
Can pelvic pain be a sign of an ectopic pregnancy?
Severe one-sided pelvic pain, especially in early pregnancy with bleeding, dizziness or shoulder-tip pain, needs urgent assessment to rule out an ectopic pregnancy. This is a medical emergency, so don't wait to be seen.
