Pregnancy Groin Pain: What It Is and Why It Matters
Pregnancy groin pain affects up to 80% of expectant mothers at some point during their journey to motherhood. If you’re experiencing sharp twinges, dull aches, or “lightning crotch” sensations in your pelvic area, you’re not alone – and more importantly, you don’t have to suffer in silence.
Quick Relief Overview:
- Most common causes: Round ligament stretching, symphysis pubis dysfunction (SPD), and pelvic girdle instability
- When it typically starts: Second trimester, though it can begin as early as the first trimester
- Safe relief methods: Pelvic support belts, gentle exercises, position modifications, and heat/ice therapy
- When to call your doctor: Severe pain, bleeding, fever, or contractions before 37 weeks
The hormonal changes and physical adaptations your body makes during pregnancy – particularly the release of relaxin hormone – cause ligaments to loosen and joints to become more mobile. While this prepares your pelvis for delivery, it can also lead to discomfort and pain that ranges from mild twinges to debilitating aches that interfere with daily activities.
As Dr. Matthew Casavant, I’ve helped countless women steer pregnancy groin pain throughout my 20+ years as a board-certified OB/GYN and founding physician of South Lake OB/GYN. My extensive training and holistic approach to women’s healthcare has shown me that with the right understanding and care plan, most pregnancy-related groin pain can be effectively managed to help you enjoy this special time in your life.
Basic pregnancy groin pain vocab:
Pregnancy Groin Pain 101
If you’ve been wondering what exactly that uncomfortable sensation in your pelvis is called, you’re asking the right questions. Pregnancy groin pain is any discomfort you feel in your pelvic area, inner thighs, or around your pubic bone during pregnancy. Think of your pelvis as a sturdy ring of bones that connects your upper body to your legs – it’s doing double duty right now, supporting both you and your growing baby.
You might be experiencing what many women colorfully call “lightning crotch” – those sudden, sharp pains that feel like an electric shock shooting through your pelvis. Or perhaps you’re dealing with a deeper, more persistent ache that seems to worsen when you walk, roll over in bed, or climb stairs.
The timing of pregnancy groin pain can be surprisingly unpredictable. While most women notice it during their second and third trimesters as their baby grows and puts more pressure on their pelvic structures, some start feeling discomfort much earlier.
What is pregnancy groin pain?
Pelvic Girdle Pain (PGP) is our catch-all term for any pain in your pelvic joints during or after pregnancy. It covers pain in the front or back of your pelvis, your buttocks, groin area, or even pain that travels down into your thighs.
Symphysis Pubis Dysfunction (SPD) gets more specific – it’s pain and instability right where your two pelvic bones meet in front. This joint normally measures about 4-5 millimeters wide but widens to about 7.7 millimeters during pregnancy to make room for your baby’s eventual journey into the world.
Round Ligament Pain (RLP) involves the thick ligaments that support your uterus and connect it to your groin area. As your uterus grows and stretches, these ligaments have to stretch too – and sometimes they protest with sharp, sudden pains that can literally take your breath away.
How common is pregnancy groin pain?
Pregnancy groin pain is incredibly common. Up to 80% of pregnant women experience some form of groin pain during their pregnancy. Pelvic girdle pain affects about 1 in 5 pregnant women to a degree that’s noticeable enough to mention to their healthcare provider. Round ligament pain occurs in up to 80% of pregnancies, though it varies widely in intensity.
Symphysis pubis dysfunction affects anywhere from 0.3% to 2.77% of pregnancies depending on which research study you look at. What these statistics tell us is that pregnancy groin pain is one of the most common pregnancy complaints worldwide, yet it often doesn’t get the attention it deserves.
Main Causes of Groin Pain During Pregnancy
Your body undergoes incredible changes during pregnancy, and pregnancy groin pain is often the result of these remarkable adaptations working overtime. The star player in this whole process is a hormone called relaxin, which your placenta releases to help your uterus and cervix prepare for childbirth.
While relaxin is essential for allowing your pelvis to expand during delivery, it relaxes ligaments throughout your entire body. When your pelvic ligaments become overly loose, the joints they normally stabilize can become wobbly and painful.
Add to this the fact that your growing baby is literally shifting your center of gravity and putting increasing pressure on your pelvic structures, and you’ve got the perfect recipe for pregnancy groin pain.
Symphysis Pubis Dysfunction (SPD)
Your symphysis pubis is the joint where the two halves of your pelvis meet in the front. During pregnancy, this joint gradually widens from about 4-5 mm to around 7.7 mm to help make room for your baby’s journey during delivery.
Sometimes this joint becomes too enthusiastic about making space. When the gap becomes excessive (over 10 mm), or when the joint becomes unstable, you develop symphysis pubis dysfunction or SPD.
Women with SPD often describe sharp, stabbing, or burning pain right at the pubic bone that can radiate into the groin and inner thighs. You might also notice clicking, grinding, or locking sensations in your pelvic area.
The pain typically gets worse with activities that require you to shift weight from one leg to another, like walking up stairs, getting out of bed, or even just standing on one leg to put on pants. For comprehensive information about this condition, check out this Scientific research on pelvic girdle pain.
Round Ligament Pain (RLP)
If you’ve ever experienced a sudden, sharp jab in your lower belly or groin that made you catch your breath, you’ve likely met your round ligaments. These strong bands of tissue stretch from your uterus down into your groin area, supporting your growing uterus.
Round ligament pain typically strikes as a sharp, jabbing sensation that’s usually felt on one side – often the right side. The pain is usually brief but intense, lasting anywhere from a few seconds to a couple of minutes.
What makes round ligament pain particularly sneaky is how it’s triggered by everyday movements. Sneezing, coughing, rolling over in bed, standing up quickly, or even laughing hard can cause these ligaments to suddenly contract, creating that unmistakable sharp twinge.
You can learn more specific strategies for managing this type of discomfort in our detailed guide on Round Ligament Pain During Pregnancy.
Other Contributors & Risk Factors
Hip and sacroiliac joint problems can send pain signals directly to your groin area. Research shows that hip joint issues refer pain to the groin in about 55% of cases.
Nerve entrapment is another potential culprit. As your uterus expands, it can put pressure on nerves that supply sensation to your groin area, causing pain, tingling, or numbness.
Don’t overlook infections as a possible cause. Urinary tract infections and vaginal yeast infections can both cause pain in the groin area, and pregnancy makes you more susceptible to both.
Certain factors increase your likelihood of developing pregnancy groin pain: high BMI, multiple pregnancies, previous pelvic injuries, history of lower back pain, physically demanding jobs, joint hypermobility, or experienced pelvic girdle pain in a previous pregnancy.
Recognizing Symptoms, Risk Factors & Diagnosis
Learning to recognize the patterns of pregnancy groin pain can help you understand what’s normal and when it’s time to call your doctor. Most groin pain during pregnancy follows predictable patterns and responds well to simple treatments.
When does pregnancy groin pain start?
First Trimester (Weeks 1-12): Some women get an early preview of pregnancy groin pain right from the start because relaxin hormone begins working immediately after conception. Early pregnancy groin pain often feels like a gentle pulling or stretching sensation.
Second Trimester (Weeks 13-27): This is prime time for pregnancy groin pain to make its debut. Your baby is growing rapidly, and your ligaments are getting their first real workout. The pain during this phase often coincides with when you start showing and feeling more baby movement.
Third Trimester (Weeks 28-40): The third trimester often brings the most intense pregnancy groin pain as your baby reaches full size and begins “dropping” into your pelvis. When your baby drops in preparation for delivery, the increased pressure on your pelvic floor and ligaments can make every step feel significant.
Who is at higher risk?
If you’re naturally very flexible or “double-jointed” (joint hypermobility), your ligaments might become excessively loose during pregnancy. Previous pelvic girdle pain is one of the strongest predictors of experiencing it again.
Your job matters too. Physically demanding work that involves heavy lifting, prolonged standing, or repetitive movements puts extra stress on your already-challenged pelvis. If you’re carrying twins or multiples, you’re essentially doing double duty, which naturally increases your risk.
A history of back pain often goes hand-in-hand with pelvic pain during pregnancy, since your spine and pelvis work as a team.
How is pregnancy groin pain diagnosed?
Diagnosing pregnancy groin pain starts with your story. We want to hear exactly how your pain feels, when it started, what makes it better or worse, and how it’s affecting your daily life.
During your physical exam, we’ll perform gentle stability tests and movement assessments. One test we often use is the Active Straight-Leg Raise test – checking how well your pelvic girdle can handle basic movements.
Ultrasound is our go-to imaging during pregnancy. It’s completely safe and can show us if your pubic symphysis has widened beyond the normal range. MRI is reserved for complex cases where we need to rule out other serious conditions.
One crucial part of diagnosis is distinguishing between normal pregnancy discomfort and symptoms that need immediate attention. Severe pain accompanied by bleeding, fever, or regular contractions before 37 weeks requires immediate medical evaluation.
Safe Relief, Treatments & Lifestyle Strategies
When you’re dealing with pregnancy groin pain, there are many safe, effective ways to find relief that won’t put you or your baby at risk. Think of managing pregnancy groin pain like tending a garden – it requires consistent, gentle care rather than dramatic interventions.
Daily Self-Care & Posture Hacks
Your daily routine holds the key to managing pregnancy groin pain effectively. Small changes can make a surprisingly big difference.
Moving with intention becomes your new superpower. Instead of jumping out of bed, try rolling to your side first, then sitting up slowly. When getting out of the car, keep your knees together and swing both legs out at the same time.
Getting dressed can become challenging when dealing with groin pain. Sitting down to put on pants and underwear eliminates the need to balance on one leg, which can trigger sharp pains.
Support becomes your best friend during pregnancy. A pillow between your knees while sleeping keeps your pelvis in proper alignment throughout the night. Adding a small pillow under your belly provides extra support and takes pressure off your groin area.
Maternity support belts can feel like a gentle hug for your pelvis. They provide just enough support to reduce the strain on your ligaments without restricting your baby’s movement.
When pain flares up, ice and heat therapy can provide quick relief. Ice for 20 minutes can reduce inflammation after activity, while heat helps relax tense muscles. Always wrap either in a thin towel to protect your skin.

Pregnancy-Safe Exercises & Physical Therapy
Gentle, targeted movement often provides the most lasting relief from pregnancy groin pain. The key is choosing activities that strengthen your supporting muscles without aggravating your symptoms.
Water becomes your sanctuary during pregnancy. The buoyancy immediately takes pressure off your pelvis, allowing you to move freely without pain. Water walking feels like magic when you’ve been struggling to walk on land.
Swimming and aquanatal classes designed for pregnant women offer the perfect combination of gentle exercise and pain relief. The weightless feeling in water often brings women to happy tears.
Core stabilization doesn’t mean intense ab workouts. Simple pelvic tilts while standing against a wall help maintain the strength your pelvis needs. Hip bridges, performed lying on your side after 20 weeks, gently strengthen your glutes and support muscles.
Kegel exercises strengthen your pelvic floor muscles, providing internal support for your entire pelvic girdle. Plus, you can do them anywhere.
Prenatal yoga offers stretches specifically designed for pregnancy challenges. Cat-cow poses improve spinal mobility, while gentle hip openers can ease tension in your groin area.

Professional Treatments & When to Call Your Provider
While self-care measures help most women manage pregnancy groin pain, sometimes you need professional support.
Physiotherapy designed specifically for pregnancy can be life-changing. Specialized pregnancy physiotherapists can provide manual techniques to improve joint function and teach you exercises custom to your specific pain patterns.
Chiropractic care from practitioners trained in pregnancy techniques can help optimize your pelvic alignment. The Webster technique, specifically designed for pregnant women, focuses on pelvic balance and optimal positioning.
Alternative therapies like acupuncture and prenatal massage offer additional relief options. TENS units, which use gentle electrical stimulation to interrupt pain signals, can also provide relief under professional guidance.
Acetaminophen remains the safest pain medication option during pregnancy when other measures aren’t enough. Always check with your provider about dosing and frequency.
However, some symptoms require immediate medical attention. Call your provider right away if you experience severe pain that prevents normal walking, any vaginal bleeding with pelvic pain, fever or chills, contractions before 37 weeks, pain with urination, or sudden onset of severe pain.
Pregnancy groin pain being common doesn’t mean you should suffer through it. There’s no need to be a hero when safe, effective relief options are available.
Frequently Asked Questions about Pregnancy Groin Pain
Can pregnancy groin pain affect labor or delivery?
Most women with pregnancy groin pain can absolutely have a normal vaginal delivery. Many patients are pleasantly surprised to find that the extra surge of relaxin hormone during labor actually helps ease their SPD discomfort when it’s time to deliver.
The key is letting your delivery team know about your pregnancy groin pain ahead of time. We’ll work with you to identify the most comfortable birthing positions – many women find that side-lying positions feel much better than traditional positions. Water births are another wonderful option that provides natural buoyancy and pain relief.
If you’re concerned about managing pain during labor, an epidural can provide excellent relief while still allowing you to have the delivery experience you want. The most important thing is including details about your pregnancy groin pain in your birth plan.
How long does pregnancy groin pain last after birth?
Most women experience significant improvement in their pregnancy groin pain within 6-12 weeks after delivery. This timeline makes sense because it takes about that long for your hormone levels to normalize and your pelvic joints to stabilize back to their pre-pregnancy state.
However, about 10% of women with SPD may continue to experience some discomfort that requires ongoing treatment. Several factors influence how quickly you’ll recover: the severity of your pain during pregnancy, whether you experienced pelvic girdle pain in previous pregnancies, your overall fitness level, and how well you’re able to follow postpartum recovery guidelines.
If your pregnancy groin pain persists beyond 12 weeks postpartum, we strongly recommend evaluation by a pelvic health physiotherapist.
Will I get pregnancy groin pain in future pregnancies?
While having pregnancy groin pain in one pregnancy does increase your risk of experiencing it again, it’s definitely not a guarantee. Each pregnancy is unique, and your body may respond differently the second or third time around.
The good news is that there are several preventive strategies you can use to reduce your risk. Maintaining good core and pelvic floor strength between pregnancies is one of the most effective approaches. Using pelvic support belts early in subsequent pregnancies – even before symptoms start – can provide the extra support your body needs. Staying active and maintaining a healthy weight between pregnancies also helps keep your pelvic structures strong and stable.
Some women benefit from preconception physiotherapy, especially if they had severe pain previously. Many of our patients tell us that being proactive with these prevention strategies significantly reduced their symptoms in later pregnancies.
