Massage is generally safe during pregnancy, and most women can enjoy it throughout all three trimesters. The American Pregnancy Association states that women can begin massage at any point during pregnancy, and the American College of Obstetricians and Gynecologists (ACOG) acknowledges prenatal massage as an option for pregnant women. That said, a few specific situations and techniques carry real risks, so knowing what to watch for matters.
First Trimester: Why Some Therapists Wait
Even though no major medical organization considers the first trimester off-limits for massage, many prenatal massage therapists won’t accept clients until the second trimester. The reasoning is twofold. First, the risk of miscarriage is naturally highest in the first 12 weeks, and some therapists worry that increased blood flow during a massage could be harmful. Second, certain pressure points on the body are thought to stimulate uterine contractions. Neither concern is backed by strong clinical evidence, but many therapists take a cautious approach and require a doctor’s release before working with first-trimester clients.
If you’re in your first trimester and want a massage, calling ahead to confirm the therapist’s policy will save you a wasted trip. Some will ask for written clearance from your OB or midwife.
Real Benefits for Pregnancy Discomfort
Prenatal massage does more than just feel good. Studies show it lowers cortisol (your body’s main stress hormone) while increasing serotonin, dopamine, and oxytocin, the brain chemicals tied to mood stability and emotional well-being. For women dealing with the anxiety and mood swings that come with pregnancy hormones, that shift can be meaningful.
Sleep is the other big win. The deep relaxation from massage often leads to better sleep quality, which in turn helps regulate energy levels and emotional stability during a time when both are in short supply. Many pregnant women also find relief from the lower back pain, hip tightness, and general muscle tension that build as the body adapts to carrying extra weight in a new center of gravity.
When Massage Is Not Safe
A small number of pregnancy complications make massage genuinely risky. The most serious is preeclampsia, a condition that develops after 20 weeks and involves dangerously high blood pressure. Preeclampsia can damage blood vessels and, in severe cases, cause stroke. Massage is contraindicated if you’ve been diagnosed with it. One warning sign to know: swelling in your face or hands (as opposed to the more typical swelling in your calves and feet) can be an early indicator of preeclampsia.
Gestational diabetes also requires caution. Blood sugar levels need to be well controlled before massage is considered safe. If you have significant varicose veins, your therapist should avoid long, gliding strokes up your legs, since varicose veins can signal blood pooling and, in some cases, a blood clot.
The Blood Clot Risk in Your Legs
This is the risk worth understanding in detail. Pregnancy puts your body into a hypercoagulable state, meaning your blood clots more easily than usual. This is a natural adaptation to protect against bleeding during delivery, but it also raises the risk of deep vein thrombosis (DVT), a blood clot that forms in the deep veins of the legs.
A case report published in BMC Pregnancy and Childbirth documented a pregnant woman with an undetected DVT whose leg massage dislodged the clot, sending it to both lungs and creating a life-threatening pulmonary embolism. The authors concluded that traditional leg massage in pregnant women should be avoided unless the woman has been confirmed to have no clot risk. This doesn’t mean all leg work is off the table, but it does mean deep pressure on the calves and thighs is something a trained prenatal therapist will approach very differently than during a standard massage. Light foot work is typically still considered safe.
Pressure Points to Avoid
Traditional Chinese medicine identifies several points on the body that are thought to stimulate uterine contractions. While the evidence is mostly based on acupuncture tradition rather than controlled studies on massage, trained prenatal therapists avoid these areas as a precaution:
- Between the thumb and index finger on the back of the hand, considered a potent point for inducing labor
- Inner lower leg, about four finger-widths above the ankle, believed to stimulate the uterus and reproductive organs
- Behind the outer ankle, in the depression between the ankle bone and the Achilles tendon
- Top of the shoulders, in the trapezius muscle halfway between the neck and shoulder joint, known for a strong “descending” action that could trigger contractions
- Lower abdomen, directly above the pubic bone
A therapist without prenatal training may not know to avoid these spots. This is one of the strongest reasons to specifically seek out someone with prenatal certification rather than booking a standard massage and mentioning you’re pregnant at the door.
Positioning During Your Massage
ACOG recommends lying on your side rather than facedown during a prenatal massage. Some massage tables have a belly cutout that lets you lie prone, but prenatal specialists tend to be cautious with these. Lying facedown can rotate the pelvic joints and increase strain on the ligaments supporting the uterus, even with a cutout.
Lying flat on your back for an extended period is also problematic. The weight of the uterus can compress the vena cava, the large vein that returns blood to your heart, causing a drop in blood pressure called supine hypotensive syndrome. Symptoms include dizziness, nausea, weakness, and shortness of breath. Side-lying avoids this entirely and maximizes blood circulation for both you and your baby.
Proper side-lying setup includes support under the hip and belly, a firm pillow between the knees to level the hips, and your spine running parallel to the length of the table. If a therapist simply has you lie on your side without these supports, the position can create its own strain. A well-trained prenatal therapist will have bolsters and pillows specifically for this purpose.
Choosing a Qualified Therapist
Not all licensed massage therapists have training in prenatal work. Prenatal certification programs, such as those approved by the National Certification Board for Therapeutic Massage and Bodywork (NCBTMB), typically involve around 24 hours of continuing education covering pregnancy complications, contraindications, safe techniques, and supervised practice with pregnant clients. This is separate from the general massage therapy license.
When booking, ask whether the therapist holds a prenatal massage certification and how many pregnant clients they regularly see. Many health spas now offer dedicated prenatal massage services staffed by therapists with this specific training. If you’re not yet showing, ACOG advises telling your therapist you’re pregnant before the session begins, since it changes which techniques, positions, and pressure levels are appropriate.
