Pregnancy Week 37: Just a Few More Days Until Your Little One Arrives!

Pregnancy Week 37: Just a Few More Days Until Your Little One Arrives!

Physician Reviewed — Not Medical Advice

Welcome! You have reached another vital milestone in your beautiful pregnancy journey. At 37 weeks, your precious little one is almost ready to make their grand entrance into the world. You might be feeling a mix of impatience, excitement, and perhaps a touch of nervousness—this is completely normal. Let’s discuss how your baby is growing this week, the physical and emotional changes you might experience, and everything else you need to know during these final days.

How is Your Baby Growing This Week?

Your little miracle is now nearly fully developed and preparing for birth each day.

Tiny Talents and Curious Responses

Your baby is now skilled enough to grasp things with their tiny fingers. They may be playing with their own fingers, toes, or even the umbilical cord. Furthermore, if a bright light shines through your uterus, your baby may actually turn their head to follow the source of light. Isn't it amazing how sensitive they have become?

Weight Gain and Body Fat

From this week on, your baby gains about 14 grams (half an ounce) per day. This weight gain is primarily due to the accumulation of fat. This layer of fat is crucial for maintaining body temperature and providing energy after birth. Generally, boys tend to be slightly heavier than girls, though this varies from baby to baby.

Your baby now likely weighs between 2.8 kg and 3 kg (about 6 to 6.5 lbs) and measures around 48 cm (19 inches) in length. In short, your baby is currently the size of a small pumpkin.

The fat deposits on your baby's body are essential for keeping them warm and protecting them from the cold during those first few days after birth.

Are the Lungs Ready? How is Brain Development?

You will be pleased to know that by this week, your baby’s lungs are largely prepared to breathe in this world. A special substance called (Surfactant) is produced inside the lungs. This prevents the lungs from sticking together and helps them expand easily when the baby takes their first breath. Because production is at a good level by week 37, a baby born now is highly unlikely to face significant breathing difficulties.

Your baby's brain and nervous system are still developing rapidly. The bones in the skull are not yet fused; this is intentional, as it allows the head to mold slightly for an easier passage through the birth canal.

Additionally, the fine hair known as lanugo that covered your baby's body has mostly disappeared, though some babies may still have a little on their shoulders or back at birth. The white, creamy coating called vernix caseosa is also fading, though it may remain in skin folds to protect their skin.

How Are You Feeling This Week?

You are in the final stretch now, and you may be experiencing a variety of sensations.

What is "Early Term"? Baby Dropping

Doctors classify the period from 37 weeks to 38 weeks and 6 days as "Early Term." This means that if the baby is born during this time, they are well-developed enough to thrive. However, "Full Term"is considered to be between 39 weeks and 40 weeks and 6 days—this is the ideal window for birth. Regardless, at 37 weeks, your baby could arrive at any time.

You may feel that your baby has dropped lower into your pelvis. This is known as "lightening." As the baby descends, the pressure on your lungs decreases, making it easier to breathe, and your heartburn may subside. However, because the baby is putting more pressure on your bladder, you will likely need to use the restroom much more frequently.

Braxton Hicks vs. True Labor

During this time, Braxton Hicks contractions—often called "false labor"—may become more frequent and intense. These are essentially practice sessions for your uterus. These contractions:

  • Do not occur in a consistent pattern and eventually subside.
  • Often fade when you change positions, drink water, or walk slowly.
  • Are usually not extremely painful.

However, true labor is quite different. Let’s look at those signs as well.

Other Common Challenges

  • Pelvic Pressure and Backache: Due to the baby dropping and the added weight, pressure in your lower abdomen, groin, and back is normal.
  • Vaginal Discharge: You may notice increased vaginal discharge. It should be white or yellowish. However, if it has a foul odor, an unusual color, or is accompanied by itching, contact your doctor.
  • Mucus Plug: You might notice a thick, jelly-like discharge, sometimes streaked with a little pink or brown blood. This is your mucus plug, which protected the cervix. Losing it does not mean labor will start instantly, but it is a sign that the cervix is beginning to prepare for birth.
  • Swelling: Mild swelling in the hands and feet is common. Avoid staying in one position for too long, elevate your legs, and drink plenty of water. However, if you experience sudden, severe swelling in your face or hands, blurred vision, or a persistent, severe headache, seek medical attention immediately as these can be signs of a serious condition like preeclampsia.
  • Insomnia: Getting a good night's sleep can be challenging. A large belly, the need to use the restroom, leg cramps, and anxiety all play a role. Try sleeping on your left side with a pillow between your legs.
  • Nesting Instinct: You may suddenly feel an overwhelming urge to clean the house, prepare baby clothes, organize supplies, or finish the nursery. This is known as the "nesting instinct." Just remember not to overexert yourself!

Preparing for This Week

The big day is just around the corner. Keep these points in mind.

The Hospital Bag and Essentials

Do a final check of your hospital bag to ensure you have everything. Make sure you have clothes for you and your baby, toiletries, diapers, medical records, and your ID. It is also important to have a plan for transportation to the hospital and to be familiar with the route.

Recognizing the Signs of Labor

Stay vigilant for these signs that true labor has begun:

  • Contractions: Unlike Braxton Hicks, these are regular, occur at consistent intervals, become progressively stronger and closer together, and last longer. They usually start as a backache that radiates to the front. Changing positions or walking will not stop these contractions.
  • Water Breaking: You may experience a trickle or a sudden gush of amniotic fluid. If this happens, go to the hospital immediately, even if contractions have not started.
  • Bloody Show:The passage of mucus with blood is a sign that labor may be approaching.

If you notice these signs, contact your doctor or head to your local hospital emergency department immediately. Additionally, if you notice a sudden decrease in your baby's movements, or if you feel fewer than 10 movements a day, report this to your doctor right away.

Rest, Nutrition, and Mental Well-being

Get as much rest as possible. If you cannot sleep well at night, nap during the day. Practice light exercise like slow walking. Eating a nutritious diet is vital. Include vegetables, fruits, greens, fiber-rich foods, and proteins (fish, eggs, dairy) in your meals. Don't forget to drink plenty of water.

It is normal to feel anxious or worried during this time. Talk to your partner, family, or a trusted friend about how you feel. Try to keep your mind calm by reading a book, listening to music, or doing something that relaxes you.

The Most Important Thing to Remember

Being 37 weeks pregnant is a critical and beautiful time filled with anticipation for both you and your baby. Your baby is ready to meet the world, and you should prepare yourself both physically and mentally to welcome this new guest.

Even if the final part of this journey feels a bit challenging, hold onto the joy of knowing that you will be cradling your precious baby very soon. Everything is worth it for that moment.

Remember, if you have any discomfort, doubts, or questions, do not hesitate to speak with your doctor or midwife. They are here to support you. Wishing you and your baby a safe and healthy delivery!
