“Everything grows rounder and wider and weirder, and I sit here in the middle of it all and wonder who in the world you will turn out to be.”
– Carrie Fisher, reflecting on the magical mystery of pregnancy.
Pregnancy is a miraculous, life-changing experience. It’s a time when your body transforms in the most incredible ways to make room for a brand-new life growing inside you. From the moment you see those two pink lines to the day you hold your baby in your arms, every week is a new adventure filled with excitement, curiosity, and physical changes — especially in your belly.
One of the most fascinating parts of pregnancy is watching your Pregnant Belly Pictures Week by Week. While each woman’s journey is unique, tracking belly growth week by week can give you insight into your baby’s development and help you feel more connected to the tiny life forming inside you.
In this detailed guide, we’ll walk you through your pregnant belly growth week-by-week, complete with fun comparisons, physical symptoms, and ideas for cherishing your bump at every stage.
When Does the Baby Bump Start Showing?
Every mom-to-be eagerly waits for the moment her pregnancy becomes visible to the world. While some start showing as early as 12 weeks, most pregnant bellies begin to visibly pop out around 16 to 20 weeks. However, this timeline varies depending on your body type, if it’s your first pregnancy, and even the strength of your abdominal muscles.
Women who’ve been pregnant before often show sooner because their abdominal muscles have already stretched. And those carrying multiples? Expect to show much earlier!
Week-by-Week Pregnant Belly Progression
Let’s take a closer look at how your belly — and your baby — changes from week to week:
Weeks 4-6: The Tiny Beginning
- Your baby is as small as a poppy seed to a blueberry.
- While you might not notice any visible bump yet, hormonal changes begin affecting your body.
- You may feel bloated or experience mild cramping, often mistaken for PMS.
- This is the time to confirm pregnancy and begin prenatal care.
Weeks 7-9: Hello, Hormones!
- Baby grows to the size of a raspberry or grape.
- You still might not see much of a belly, but the uterus is expanding.
- Morning sickness, fatigue, and emotional ups and downs are common.
- Your lower abdomen may feel fuller or firmer, hinting at changes ahead.
Week 10-12: Subtle Changes
- Baby is about the size of a prune to a lime.
- Some women begin to notice a slight bump — often more bloating than baby.
- The uterus has grown to the size of a grapefruit and may push against your bladder.
- You might start taking weekly belly photos to document your journey — this is where your “belfie” game begins!
Week 13-16: First Bump Sightings
- Your baby now resembles a lemon to an avocado.
- This is often when the bump becomes more noticeable, especially by the end of week 16.

Week 21-24: Glowing and Growing
Baby grows to the size of a cantaloupe or corn.
- Your belly is now round, firm, and very obvious. Strangers may start offering you a seat!

- You’re likely embracing your pregnancy glow and taking lots of photos.
Week 25-28: Entering the Third Trimester
- Baby is about the size of a cauliflower to a large eggplant.
- The belly now measures 25-30 cm from pubic bone to the top of the uterus (fundal height).

- Backaches and leg cramps might kick in — gentle stretching and rest can help.
Week 29-32: The Belly Takes Over

- Your bump is getting heavier, and your center of gravity shifts — be cautious with movements.

Week 33-36: Preparing for Arrival
- Baby measures around 17-19 inches, weighing up to 2.5 kg.
- Your bump now hangs a bit lower as the baby starts moving into a head-down position.
- You may experience Braxton Hicks contractions — your body’s way of rehearsing for labor.
- Time to pack your hospital bag and set up the nursery!
Week 37-40: Full Term and Fabulous
Your baby is around 19-22 inches long and weighs between 3 to 4 kg.
- The belly might not grow much more, but you’ll feel tighter and more stretched.
- Many women feel pelvic pressure, difficulty sleeping, and a strong nesting instinct.
- You’re on baby watch now — every twinge feels like it could be the moment!
Loving and Embracing Your Pregnant Belly
As your body changes, it’s easy to feel overwhelmed by your growing shape. But remember — you’re creating life! Here are some sweet and simple ways to celebrate your belly and bond with your baby:
1. Massage Your Bump
Use natural oils like almond or coconut oil to keep the skin supple and hydrated. It’s also a relaxing way to bond with your baby.
2. Take Weekly Bump Photos
Track your growth by snapping pictures each week. It’s a fun way to look back at how far you’ve come.
3. Practice Prenatal Yoga
Gentle stretching improves flexibility, posture, and body awareness — while also relieving common pregnancy discomforts.
4. Go Swimming or Join Aqua Natal Classes
Water workouts reduce stress on joints and provide gentle resistance, perfect for pregnant bodies.
5. Create a Pregnancy Journal
Write down your thoughts, cravings, mood swings, and moments of joy. This can be a cherished keepsake or even passed down to your baby someday.
Is Every Bump the Same?
Absolutely not! Your baby bump’s shape, size, and rate of growth depend on:
- Your height and body structure
- Whether it’s your first or subsequent pregnancy
- The baby’s position
- Amniotic fluid levels
- If you’re carrying multiples
So don’t worry if your belly looks different from someone else’s — trust your body and rely on your doctor’s checkups to track healthy growth.
Final Thoughts: Celebrate Your Belly Journey
Pregnancy is an incredible transformation — physical, emotional, and spiritual. Your belly is more than just a bump; it’s the home of a tiny heartbeat, tiny feet, and a whole future waiting to unfold.
Whether you’re documenting each week with selfies or simply marveling at the changes in the mirror, take a moment to admire what your body is doing. You are strong, beautiful, and glowing — all while growing a human being.
So, embrace every stretch mark, every bump, and every flutter. Your pregnant belly tells the story of love, strength, and life itself.
