If you're pregnant and feeling like someone's squeezing your ribs in a tight hug that won't let go, you're definitely not alone. Rib discomfort during pregnancy is common, though estimates vary — studies of general musculoskeletal pain (including rib area) suggest that about 50-70% of expectant mothers experience some form of upper body or rib-area discomfort, especially during the second and third trimesters. While it can be pretty uncomfortable, the good news is that it's usually completely normal and there are plenty of ways to find relief.
Your baby is growing larger, and that might make your ribs feel a little rattled. But relax - we'll tell you why that is, when that tends to occur, and best of all, what you can do about it.
Why Rib Discomfort During Pregnancy Happens
Determining what is causing you discomfort with rib pain means that you can be more relaxed when addressing it. The body goes through some amazing changes during pregnancy, and the ribcage area gets affected in some various ways.
Main Causes
The most probable explanation for why your ribs would hurt when you are pregnant is that the expanding uterus. As the baby grows, especially after the 20th week, the uterus presses against both your ribs and diaphragm. It's a bit akin to packing a watermelon into a spot meant for a cantaloupe—something has to compromise, and unfortunately, that something is frequently your comfort.
Your little one is a kicker and a stretcher, and those little feet are a force to be reckoned with if they connect with that ribcage. Most moms say that their baby seems to be stretching their ribs from the inside out, and that's pretty close to the truth.
Body Changes
Hormones during pregnancy, and particularly relaxin, make the ligaments that connect your sternum and rib cage to your spine loose. Consequently, when your rib cage becomes more spacious for accommodating a widening uterus and a re-developing set of lungs, the area may be uncomfortable and feel unstable.
Your posture shifts when your center of gravity moves forward. A lot of pregnant women don’t even realize they’re arching their backs or pulling their shoulders back to balance out their growing belly, and that can really strain the rib muscles and joints.
All these factors together make for a really tough time with rib discomfort, but just keep in mind - your body is doing its thing to keep you and your baby healthy.
When Rib Discomfort During Pregnancy Usually Starts
Most women first notice rib discomfort during pregnancy around weeks 24-28 of the second trimester, when the uterus rapidly grows and pushes against the lower ribs. The pain typically worsens during the third trimester, peaking around weeks 32-36, then often improves in the final weeks as the baby drops lower. However, every pregnancy is different — some women feel mild tenderness as early as around week 20, while others don't experience it until much later. Your height, baby's position, and whether this is your first pregnancy can all influence the timing and severity of rib discomfort.
How to Relieve Rib Discomfort During Pregnancy
The great thing about rib discomfort is that we have plenty of effective and safe means to obtain some alleviation. The following simple steps can significantly make you feel better while you are carrying a baby.
Step 1: Quick Relief Tips
Once rib distress arises, stretches for gentle relief are available immediately. Raise the side hurting arm up and over the head and lean away from the pain. Hold for 15-30 seconds and repeat if needed. This simple movement may create space between the ribs and rest the muscles.
Another quick relief trick is the "cat-cow" stretch from yoga. Get on your hands and knees, and then slowly arch your back up like a cat, and then just let it sag down gently. This move really helps to realign your spine and can chill out that rib pressure.
Step 2: Heat and Cold Use
Heat and cold therapy is a rib comfort miracle for pregnancy. Try placing a warm compress or heating pad on low for 15-20 minutes to relax strained muscles. Just be sure it isn't blisteringly hot - you should be able to comfortably lay a hand on the heat.
For inflammation or sharp pain, apply a cold pack wrapped in a thin towel for 10 to 15 minutes. Do not apply ice right to the skin, and don't use a heating or cooling measure for a greater duration than recommended.
Step 3: Breathing Tips
Breathing properly can make a world of difference in that rib ache. Take some slow abdominal breaths; just place one hand on the chest and one on the stomach. Breathe in slowly through the nostrils and make certain that the belly hand rises higher than the hand on the chest.
Try the "4-7-8" breathing technique: breathe in for four beats, hold for 7, and breathe out for 8. This relaxes the diaphragm and may alleviate rib strain.
Step 4: Better Posture
Correct posture is significant for the alleviation of rib pain. Sit in a high-backed supporting chair and refrain from slouching. Hold the shoulders down and back and imagine a string tugging at the top of the head to the ceiling.
When you are standing, keep your weight centered between both feet and do not lock your knees. When you must stand for a while, use one foot on a small stool or step to ease strain on your lower back. For extra support while doing day-to-day tasks, the Momcozy Ergonest Maternity Belly Band minimizes rib pressure while giving maximum tummy support.
Step 5: Sleep Positions
Positioning during sleep can make a significant impact on rib comfort. Sleep side (better on the left side) with a pregnancy pillow between your knees and another under your abdomen for support. Some get relief by propping up their upper body with a pillow.
Don't lie on your back after 20 weeks, as gravity could compress significant blood vessels and make rib tenderness worse. As a compromise, when side sleeping, use a recliner or adjustable bed if available.
Step 6: Daily Lifestyle Adjustments
Choose some loose, relaxed clothing that doesn't bind around your ribs. Avoid underwire bras and opt for gentle, supporting maternity bras. You may also find that high-waithed pants that rest just below your ribs take some pressure off.
Vary your activity to reduce motion that worsens rib strain. Stand up frequently while you are sitting or standing, and avoid lifting strenuously or twisting motion that stretches rib muscles.
When to See a Doctor for Rib Discomfort During Pregnancy
Whereas rib pain is normally fine, sometimes you should go and see a doctor to make sure that both you and your baby are okay.

Mild, shifting rib aches are usually part of normal pregnancy changes. But if the pain is severe, constant, or paired with alarming symptoms, seek medical help right away.
When to Call Your Doctor
If you suddenly get this intense rib pain, like really bad, definitely reach out to your doctor right away, especially if you also feel short of breath, dizzy, or have chest pain. Those could mean something serious, like preeclampsia or a pulmonary embolism.
Call also if the rib hurts a lot and interferes with eating, sleeping, or activity, or if a fever or temperature and rib hurting develop, as these may be signs that an infection has developed.
Frequently Asked Questions
Q1. Can Rib Pain During Pregnancy Injure the Baby?
No, usual rib pain during pregnancy is perfectly fine for the baby. It's just the body making room for your expanding tummy and baby. But if you feel sharp pains or other alarming signs, it is better to talk to the doctor just to make sure everything is fine.
Q2. Is Rib Pain Worse on One Side?
Yes, it's completely normal for rib discomfort during pregnancy to be worse on one side. This often depends on your baby's position - if they're lying more to one side or frequently kicking in one direction, you'll feel more discomfort there. The pain can also shift sides as your baby moves and grows. Using supportive products like the Momcozy Ergonest Maternity Belly Band can help distribute weight more evenly and reduce one-sided strain.
Q3. Will Rib Pain Go Away After Delivery?
The majority of women find that their rib pain in pregnancy gets better within a few weeks after delivery as the organs regain their non-pregnant positions. It may, however, take a few months for certain changes that were felt during pregnancy to go away completely, especially if you are lactating, as some hormones are still elevated. For new mothers, using an efficient pumping setup like a Double breast pump can also help reduce postural strain by shortening the time spent in one position.
