You can get a prenatal massage right up until your due date. There is no specific week cutoff. A systematic review of randomized controlled trials found that healthy women with uncomplicated pregnancies can receive massages during the entire course of pregnancy. As discomforts peak in the final weeks, many women actually increase their frequency to once a week.
Why the Third Trimester Is Peak Time
Most of the reasons people seek prenatal massage intensify in the last two months. Sciatic nerve pain from the extra weight and shifting position of the baby is one of the most common complaints. Swelling in the calves and feet typically appears halfway through pregnancy and worsens as the due date approaches. Massage during this period can reduce that swelling, ease sciatic pain, and help with insomnia.
Sessions generally last anywhere from 15 minutes to an hour. If you’ve been getting occasional massages earlier in pregnancy, the Cleveland Clinic notes you can safely increase to once a week as the third trimester progresses and discomfort builds.
Pressure Points and Labor Concerns
One of the biggest worries people have about late-pregnancy massage is accidentally triggering labor. Certain acupressure points, particularly on the inner ankle and the hand between the thumb and index finger, have a reputation for inducing contractions. The actual evidence doesn’t support this fear. A Cochrane review examining multiple trials of acupressure for labor induction found no benefit in any outcome measured: no reduction in cesarean sections, no effect on time to delivery, no increase in spontaneous labor. The mechanism is still speculative, and the data consistently shows that pressing these points does not reliably start labor.
A skilled prenatal massage therapist will still avoid these areas as a precaution, but if you’re worried that a massage at 38 or 39 weeks will send you into labor, the evidence suggests that’s very unlikely.
What Changes in Late Pregnancy
The massage itself looks different in the final weeks compared to earlier trimesters. Lying face down is off the table entirely, and lying flat on your back for more than a few minutes can compress a major vein that returns blood to the heart, causing dizziness and reduced blood flow to the baby.
Most therapists use side-lying positioning, with you resting on your left side supported by pillows. A firm bolster goes between the knees to keep the hips aligned, a small pillow supports the waist to prevent side-bending, and a soft wedge may be tucked under the front edge of the belly to create a gentle hammock effect without compressing the uterus. For women who find full side-lying restrictive late in pregnancy, a semi-reclined position with the upper body elevated 30 to 45 degrees is a common alternative, especially helpful if you’re dealing with reflux or breathlessness.
Deep tissue work is also modified. Therapists avoid deep pressure on the legs and arms to prevent dislodging blood clots, and the abdomen is never massaged due to the risk of uterine or placental injury. Highly concentrated essential oils are generally skipped as well, since some are suspected of stimulating contractions.
When You Need Medical Clearance First
The “anytime until your due date” guideline applies to uncomplicated pregnancies. If your pregnancy involves complications like preeclampsia, placenta previa, or a history of preterm labor, you’ll need your OB’s approval before booking a session.
The most serious concern is undetected deep vein thrombosis (a blood clot in the leg). Pregnancy creates a natural state of increased blood clotting, which means some women develop clots without obvious symptoms. Massaging a leg that contains a clot can dislodge it and send it to the lungs, a potentially fatal event called a pulmonary embolism. A case report published in the National Library of Medicine documented exactly this scenario and recommended that pregnant women avoid leg massage unless thromboembolism has been ruled out.
Signs that warrant a call to your provider before getting a massage include:
- One-sided leg swelling that looks noticeably different from the other leg, especially with warmth, redness, or tenderness in the calf
- Sudden, severe swelling in the face or hands, which can signal preeclampsia
- Vaginal bleeding or unusual discharge
- Regular contractions before 37 weeks
Finding a Qualified Therapist
Not every massage therapist is trained in prenatal work, and the differences matter more in the final weeks. A therapist with prenatal certification will know how to position you safely, which areas to avoid, how to adjust pressure for the changes in your circulatory system, and how to recognize warning signs during a session. Many spas and massage practices list prenatal massage as a specific service, and it’s worth confirming that the therapist has dedicated training rather than just general experience.
If you’re past 37 weeks and feeling nervous about timing, keep in mind that the research supports massage safety throughout the entire pregnancy for healthy women. The final month is when your body is under the most physical strain, and it’s often when massage provides the most relief.
