What’s happening with the baby at 36 weeks pregnant?

Lungs are ready

Your baby’s lungs are fully developed and ready for their first breath. When they inhale for the first time after birth, their lungs will expand, and any fluid in the air sacs will be replaced with air.

Hardening bones

Your baby’s bones are continuing to harden, though they’re still softer and more flexible than an adult’s. This flexibility helps during delivery and will gradually strengthen as they grow.

Shedding lanugo and vernix

The fine hair (lanugo) and protective waxy coating (vernix caseosa) covering your baby’s skin are being shed. Your baby swallows these, along with other secretions, which form their first stool, called meconium.

Positioning for birth

Most babies are now head-down, facing your spine, in preparation for delivery. If your baby is still in a breech position, your provider might attempt a manual procedure to turn them.

How big is your baby at 36 weeks pregnant?

At 36 weeks pregnant, your baby is about the size of a head of romaine lettuce. They measure approximately 47.3 cm from head to toe and weigh around 2.81 kg. Your baby continues to gain weight, adding about 140 to 200 grams each week, helping them build the fat needed to stay warm after birth.

How is your belly at 36 weeks pregnant?

At 36 weeks pregnant, your belly is likely feeling heavy and stretched as your baby reaches their final growth stages. 

Size and changes

• Your uterus has grown significantly and now reaches up to your rib cage, crowding your internal organs. This can cause discomfort like heartburn and shortness of breath.

• If your baby has dropped into your pelvis (lightening), you might feel some relief in your breathing but more pressure in your lower abdomen and bladder.

Appearance

• Linea nigra: The dark vertical line down the center of your belly may still be visible due to hormonal changes.

• Stretch marks: Rapid stretching of the skin may cause new or more prominent stretch marks. Keeping your skin moisturized can help reduce itching.

Sensations

• Braxton Hicks contractions may make your belly feel tight or hard at times as your body prepares for labor.

• You may also feel sharper, jolting pains in your pelvis or vagina (known as lightning crotch) as your baby’s head presses on nerves.

Common symptoms and how to manage them?

1) Cramping

Mild cramping is common at this stage and is often caused by Braxton Hicks contractions or your body preparing for labor. It can also stem from bloating, constipation, or round ligament pain.

How to manage: Rest when needed, stay hydrated, and use a warm compress on your lower abdomen for relief. Call your provider if cramps are regular, accompanied by back pain, or if you suspect early labor.

2) Vaginal discharge

As labor approaches, you may notice an increase in discharge or the loss of your mucus plug. It can appear clear, pinkish, or slightly bloody.

How to manage: Use panty liners for comfort, and contact your provider if you notice unusual discharge, heavy bleeding, or suspect your water has broken.

3) Dizziness

Your growing uterus can put pressure on blood vessels, slowing circulation and causing lightheadedness. Hormonal changes can also affect your balance.

How to manage: Stand up slowly, eat regularly to maintain blood sugar levels, and stay hydrated. Avoid lying flat on your back.

4) Pelvic pain

As your baby drops lower into your pelvis, you may feel sharp or dull pain in your hips, groin, or lower back. This discomfort can intensify with movement or pressure.

How to manage: Wear a pregnancy support belt, practice good posture, and try warm baths or prenatal stretches to alleviate pain.

5) Heartburn

Your uterus pressing against your stomach can cause acid reflux or heartburn, especially after eating.

How to manage: Eat smaller, frequent meals, avoid trigger foods (spicy, fatty, or acidic), and prop yourself up while sleeping. Ask your provider about pregnancy-safe antacids if needed.

6) Swelling

Mild swelling in your hands, feet, or face is normal as your body retains more fluid. However, sudden or severe swelling could indicate preeclampsia.

How to manage: Rest with your feet elevated, avoid standing for long periods, and stay hydrated. Notify your provider if swelling becomes severe or is accompanied by headaches or vision changes.

7) Fatigue

The physical demands of late pregnancy and interrupted sleep can make you feel exhausted.

How to manage: Take naps during the day, ask for help with daily tasks, and practice good sleep hygiene by using pillows for support and creating a calming bedtime routine.

Frequently asked questions at 36 weeks pregnant

Is it normal to feel cramping now?

Yes, mild cramping is common and can result from Braxton Hicks contractions, bloating, or round ligament pain. However, cramping accompanied by regular contractions, back pain, or changes in discharge could indicate early labor. Contact your provider if you’re unsure.

What should I do if my baby is still breech?

If your baby is in a breech position, your healthcare provider might recommend a procedure called external cephalic version (ECV) to try and turn your baby head-down. This is usually done around 36-37 weeks.

What happens if I go into labor this week?

Babies born at 36 weeks are considered "late preterm." While they may need some extra care, most are healthy and do well after birth. Your provider will monitor for signs of labor and guide you on when to head to the hospital.

Why do I feel so much pelvic pressure?

As your baby drops lower into your pelvis, it’s normal to feel increased pressure in your lower abdomen and pelvis. This is called lightening and is a sign that your baby is getting ready for birth.

Is it safe to travel at 36 weeks?

Most healthcare providers recommend avoiding travel at this stage, especially long trips. If you must travel, consult your provider first and ensure you have access to medical care if needed.

Should I be concerned about dizziness?

Dizziness is common due to changes in blood circulation and hormones. Standing up slowly, eating regularly, and staying hydrated can help. However, if dizziness is frequent or severe, contact your provider to rule out any underlying issues.

What do I need to pack in my hospital bag?

Include essentials like your insurance card, toiletries, comfortable clothing, a phone charger, and a going-home outfit for your baby. Leave valuables and unnecessary items at home.
