37 Weeks Pregnant: Early Term and Ready for Birth

At 37 weeks pregnant, your baby is about the size of Swiss chard and pregnancy has reached an important milestone. This stage is considered early term, meaning your baby is continuing to mature but is also approaching full readiness for life outside the womb.

If you are searching for 37 weeks pregnant baby size, symptoms, or signs of labor, this week marks a transition from preparation to readiness.

Birth could happen anytime in the coming weeks.

At a Glance:
37 Weeks Pregnant
  • Baby size: about the size of Swiss chard
  • Trimester: third trimester
  • Key hormonal shift: oxytocin and prostaglandins begin playing a greater role as the body prepares for labor.
  • Common symptoms: pelvic pressure, frequent urination, swelling in the feet or ankles, back discomfort, heartburn, and difficulty sleeping.
  • Doctor visit: weekly prenatal visits usually continue from this point forward
  • Emotional theme: awareness shifts toward readiness as birth begins to feel very near.

At 37 weeks pregnant, your baby measures about 48 to 49 cm from head to heel and weighs around 2.9 to 3.2 kilograms (about 6.3 to 7 pounds).

Here is what is happening:

• the lungs are now typically mature enough to support breathing after birth
• the brain continues developing and will keep growing after birth
• the baby continues building body fat for temperature regulation
• reflexes such as sucking and grasping are well developed
• the baby practices breathing movements inside the uterus
• most babies are positioned head down in preparation for delivery

Your baby is now considered early term and continuing the final stages of preparation for birth.

What Is Happening in Your Body at 37 Weeks Pregnant

Your body is entering the final stage of pregnancy and preparing for labor.

You may notice:

• increased pelvic pressure
• frequent urination as the baby presses on the bladder
• swelling in the feet or ankles
• stronger Braxton Hicks contractions
• back discomfort
• difficulty finding comfortable sleeping positions

Some women may also notice lightening, when the baby moves lower into the pelvis.

Emotional and Nervous System Changes

As birth approaches, attention often shifts from pregnancy to the upcoming experience of labor and meeting your baby.

You may experience:

• excitement about the approaching birth
• heightened awareness of your body’s signals
• moments of impatience or anticipation

Creating moments of calm can help support your nervous system during this transition.

Sit comfortably and place one hand on your belly.

Take a slow breath in through your nose and allow your belly to gently expand.

Exhale slowly and imagine releasing any tension in your body.

Feel the steady presence of your breath and the quiet strength of your body.

Stay here for several slow breaths and allow yourself to relax.

Preparing for Birth

At this stage of pregnancy, many parents begin focusing more intentionally on the experience of labor.

Approaches such as hypnobirthing emphasize breathing, relaxation, and working with the body’s natural rhythms during birth.

These techniques can help reduce tension and support a calm, focused mindset during labor.
