37 Weeks Pregnant

Length of baby: 48cm
Weight of baby: 2.8kg
At week 37, your baby is almost ready to meet the world, and is now practising sucking, gripping, blinking, inhaling and exhaling.


This week, your baby is considered early term. Here is how you classify which term you are at:

Before week 37 – Preterm

Week 37 to 38 – Early term

Week 39 to 40 – Full Term

 Week 41 – Late Term

Week 42 – Post Term

During this period of time you may find an overwhelming urge to clean and get your home ready for the baby.

This is known as nesting, and is a woman’s instinct as you prepare for birth.

Nesting is not harmful to you or your baby, but do avoid any dangerous situations such as climbing on a ladder to clean or carrying heavy objects. Whatever you do, always remember to keep yourself and baby safe while nesting.

37 weeks pregnant is how many months? 37 weeks pregnant is nine months and one week pregnant. You got about three weeks till your due date.



How big is baby at 37 weeks? Your baby is the size of a winter melon, which is about 48cm.

The current weight of your baby is about 2.8kilograms.



This is the weight gain that you must achieve this week.

Underweight(BMI <18.5)  0.44kg to 0.58kg
Normal weight(BMI 18.5 to 24.9)0.39kg to 0.50kg
Overweight(BMI 25 to 29.9) 0.23kg to 0.33kg
Obese(BMI ≥ 30) 0.16kg to 0.25kg



You are now very close to giving birth, and you will experience symptoms because of your baby dropping lower into your pelvis region.

Being 37 weeks pregnant, here are some signs and symptom that your body might be experiencing:

  • Braxton Hicks Contractions. You will realise that contractions are coming on more frequently. Be sure to understand the early signs of labour – contractions that come every five minutes and last for at least an hour. Stay hydrated too, because being dehydrated could cause you to go into early labour.
  • Increase in Vaginal Discharge. You will experience an increase in vaginal discharge as your body prepares for delivery, but if you spot a bloody and mucus-like discharge, it could be your mucus plug and this would mean you are not far off from labour.
  • Trouble Sleeping. You might be facing trouble sleeping and can find yourself staring at the ceiling at night. Try to get some exercise in the day and drinks lots of water.
  • Intense dreams. When you do manage to fall asleep, you might find yourself having weird dreams. Anxiety about becoming a parent and being worried about labour can do weird things to your subconscious mind.
  • Lower Backache. As your baby drops towards your lower pelvic region, this puts pressure on your lower back causing some new aches.
  • Stretch Marks. You might find new stretch marks appearing on your pregnant belly.
  • Breast Changes. Your breast is now a lot bigger, and your nipples will protrude more now to prepare it to feed your baby once it is born.


You will not be full term till two weeks from now, and these two weeks will allow the baby to fully develop it’s brains and lungs. So if you are planning a caesarean section, do it after week 39 unless medically necessary. 



It may be difficult to get comfortable to fall asleep at night due to your bulging belly. Do take it slow throughout the day and do not over exert yourself, especially if you are not sleeping well.

At this stage, remember to watch out for the signs of labour. You do not want to wait till it’s too late before knowing you are going into labour. You are still considered early term, so if you’re wondering how to induce labour, unfortunately, it is not time yet.

Even if you plan to undergo a c-section, you should wait at least two more weeks till full term at week 39.

This is because some babies need more time to complete development, and can make a big difference in the overall health of the baby.

Here are some 37 weeks pregnant signs of going into labour:

  • Water breaking. If you feel water leaking from your vagina in a slow trickle or gush, that is probably amniotic fluid and you will go into labour within 12 hours. If your water has broken, you should call your doctor and get to the hospital.
  • Contractions. If you are having contractions, remember to watch out for contractions that happen within five minutes apart for at least an hour. Thereafter when you get into active labour where contractions become stronger and you should be at the hospital by then.
  • Vaginal discharge. When you pass out your mucus plug, which is a bloody thick red/pink/brown mucus-like lump, you will soon go into labour.



Your baby is almost ready to meet the world, and is now practising sucking, gripping, blinking, inhaling and exhaling.

He or she will spend the next two weeks developing his or her lungs and brains, so if you are doing a c-section, it is best to wait till at least week 39 (unless it’s an emergency).

If you are wondering what your baby will look like, your baby may look quite different from the parents, at this initial stage.  



Reminders for the week:

  • Read up on postpartum depression
  • Get ready your baby nursery
  • Schedule next week’s prenatal visit
  • Take a photo of you and your baby bump for memory
