Introduction

You’ve made it to the 37th week of pregnancy—congratulations! This is an exciting milestone as your baby is now officially considered full-term.

Labor could start anytime, but whether you have weeks or just days left, there’s plenty happening in your body and with your baby.

This guide will walk you through the key developments, what to expect from your body, signs of labor, and how to prepare for the big moment.

Baby’s Development at 37 Weeks

Your baby is completing the finishing touches and getting ready for life outside the womb. Here’s a closer look at their progress this week.

1.Size and Weight
At 37 weeks, your baby is about the size of a small pumpkin or a head of romaine lettuce. They weigh approximately 6 to 6.5 pounds and measure around 19 inches long, although this can vary.

2.Key Developments

• Lung Maturity: Your baby’s lungs are now fully developed and capable of supporting them in the outside world.
• Fat Stores and Temperature Regulation: Fat continues to build up under the skin, which will help your baby maintain their body temperature after birth.
• Brain and Nervous System: The brain is still growing rapidly. These final weeks are critical for brain development that will support functions like breathing and feeding.

3.Positioning

By the 37th week, most babies settle into the head-down position, preparing for a vaginal delivery.

If your baby remains in a breech position (feet or buttocks down), your doctor might discuss options like an external cephalic version (ECV) to turn the baby.

While your baby is getting ready, your body is undergoing its own series of changes to prepare for labor and delivery.

1.Physical Changes

• Pelvic Pressure: As your baby moves lower into your pelvis in preparation for birth (a process called lightening or engagement), you might feel increased pressure in your lower abdomen and groin.
• Cervical Dilation: Your cervix may begin softening, thinning (effacement), and dilating. These are early signs that your body is preparing for labor.
• Braxton Hicks Contractions: The irregular “practice” contractions may feel more pronounced this week as your uterus gets ready for labor.

Frequent Urination and Back Pain: The baby’s position can put pressure on your bladder and spine, leading to more trips to the bathroom and occasional backaches.

2.Emotional Changes

Many expectant mothers feel a mixture of excitement and nervousness at this stage. It’s completely normal to feel occasional fatigue, mood swings, or anxiety about labor.

You may also notice a burst of energy to clean and organize—a behavior called nesting—motivated by a desire to prepare for your baby’s arrival.

At 37 weeks, it’s helpful to be informed about the potential signs of labor. Here’s what you should monitor in the coming days or weeks.

1.Regular Contractions
True labor contractions are different from Braxton Hicks. They are typically stronger, more regular, and continue to intensify over time.

2.Loss of the Mucus Plug
This jelly-like plug seals your cervix during pregnancy. Losing it can be a sign that labor is approaching, but it’s not a guarantee that it will begin immediately.

3.Water Breaking
A sudden gush or trickle of fluid could indicate that your amniotic sac has ruptured. If this happens, contact your healthcare provider and get ready to head to the hospital.

4.Bloody Show
A pink or bloody discharge might be another signal that your cervix is beginning to prepare for delivery.

This is the time to finalize preparations and make sure you’re physically and emotionally ready for childbirth.

1. Finalize Your Birth Plan

Review your birth plan with your doctor, including your preferences for pain relief, delivery positions, and any specific requests for the delivery room.

2. Pack Your Hospital Bag

Make sure your bag is ready with essentials like comfortable clothes, toiletries, snacks, baby clothes, diapers, and any documents your hospital may require.

3. Ensure Transportation

Plan how you’ll get to the hospital when labor begins. If you have other children, make arrangements for their care during your delivery.

4. Stay Active, But Rest

Light exercises like walking or prenatal yoga can help you stay limber and reduce stress. Balance activity with rest—taking short naps or relaxing as needed.

5. Track Baby Movements

Your baby should still be active, even though they have less room to move. Pay attention to their kicks and rolls, and contact your doctor if you notice a significant decrease in activity.

Self-Care Tips for the 37th Week

Taking care of yourself can make these final weeks more comfortable.

• Relieve Discomfort
  Use pillows to support your back and belly when lying down. Warm baths and gentle massages can also ease muscle tension.
• Stay Hydrated
  Drink plenty of water to avoid dehydration, which can sometimes trigger false labor contractions.
• Eat Nutritious Foods
  Focus on a balanced diet with iron, calcium, and protein to keep your energy up. Smoothies, soups, and healthy snacks are easy options.
• Practice Stress Management
  Deep breathing, meditation, or listening to calming music can help you manage any anxiety you’re feeling as the big day approaches.

It’s important to know when to seek medical attention during the 37th week. Call your doctor immediately if you experience any of the following symptoms:

• A sudden decrease in baby movements.
• Intense or continuous abdominal pain.
• Heavy vaginal bleeding.
• Severe swelling, especially in your hands or face, which could signal preeclampsia.
• Any vision changes, such as blurriness or seeing spots.
• Signs of labor, especially if your water breaks or contractions become regular and painful.
