5th Month of Pregnancy: Baby Movements, Anatomy Scan & Most Common Questions Moms Ask in Weeks 17–20
- by ["Dr. Priyanka Mehta"]
Congratulations! You've made it to the second trimester's golden phase—the 5th month of pregnancy! This is one of the most exciting periods of your journey. Your baby is becoming more real to you than ever before, and your body is going through fascinating changes. Let's dive into what weeks 17-20 hold for you and your little one.
What's Happening to Your Baby This Month?
The Big Milestone: Baby Kicks Are Here!
By week 17, many expecting moms experience something magical—baby kicks! If you're a first-time mom, you might mistake them for gas or butterflies in your stomach. But trust us, once you feel it, you'll know the difference. That flutter, that tiny punch, that little roll—it's your baby moving inside you. Your little one is now around 5-6 inches long and has the freedom to move around in the amniotic sac. They're flexing their muscles, learning how to move their limbs, and preparing for life outside the womb. It's like their first gym session! If you haven't felt movements yet, don't worry. Some moms feel them as early as week 16, while others don't until week 20 or beyond. It depends on where your placenta is positioned, your body type, and even how attentive you are to the sensations.
The 20-Week Anatomy Scan—Meeting Your Baby
The big highlight of the 5th month is the 20-week ultrasound, also called the mid-pregnancy scan or anatomy scan. This isn't just a regular check-up—it's the scan where doctors examine your baby in detail.
- The sonographer checks your baby's head, brain, face, spine, heart, lungs, stomach, kidneys, and limbs
- They measure your baby to confirm due date accuracy
- They check the placenta's position and the amount of amniotic fluid
- They look at the umbilical cord connection
- They assess the baby's overall growth and development
Your Body Changes in Months 5
The Growing Belly is Real Now
By this month, there's no hiding your pregnancy anymore. Your belly is noticeably round, and you might be gaining about a pound per week. This is normal and healthy! You're not just gaining fat—your baby, placenta, amniotic fluid, and increased blood volume all add up. Many moms feel their most beautiful during this phase. The glow is real, and you can finally wear those cute maternity clothes without people wondering if you just ate too much pizza.
Back Pain Is Starting—And It's Not Your Imagination
Welcome to one of the most common complaints of the 5th month: back pain. Your growing belly shifts your center of gravity forward, making your back muscles work overtime. Add pregnancy hormones (especially relaxin, which loosens your ligaments) to the mix, and you've got the perfect recipe for discomfort.
Why it happens:
- Your belly weight pulls you forward
- Hormones soften the ligaments that support your spine
- Your posture naturally changes as you try to balance your growing bump
- You're carrying extra weight that you're not used to
Ways to ease it:
- Wear supportive, comfortable shoes (no high heels, sorry!)
- Take warm baths—heat therapy is your friend
- Sleep on your side with a pillow between your knees
- Avoid lifting heavy objects
- Gentle prenatal yoga or swimming can be incredibly helpful
Round Ligament Pain—The Sharp Jabbing Sensation
Expect sharp, shooting pains in your lower belly or groin area? That's likely round ligament pain. The round ligaments support your uterus, and as your uterus grows, these ligaments stretch and thicken to accommodate it. This pain is completely normal and doesn't mean anything is wrong with your baby. It usually lasts only a few seconds but can be startling. Some moms describe it as a sudden stitch or stabbing feeling.
To manage it:
- Slow down if you're moving too quickly
- Change positions gradually
- Apply a warm compress
- Wear comfortable, loose clothing that doesn't put pressure on your belly
Sleep Position Matters Now
Don't sleep on your back in the later months. By the 5th month, it's a good time to start training yourself to sleep on your side, preferably the left side.
Why left side is best:
- It improves blood flow to your baby
- It reduces pressure on your liver
- It helps with kidney function and reduces swelling
Side sleeping can feel uncomfortable at first, but it becomes easier when you have the right support. A pregnancy pillow between your knees, under your belly, and behind your back can make a world of difference. It keeps your spine aligned and prevents that "falling forward" sensation that many side-sleeping pregnant women experience.
The Most Common Questions Moms Ask in Month 5
"Why Do I Feel Movements But Then They Stop?"
This is super common and totally normal. Your baby sleeps—a lot! They have sleep cycles just like you do. They're also still small enough that their movements might not be consistently strong. As your pregnancy progresses, movements become more regular and noticeable. However, if you've been regularly feeling movements and suddenly they stop for more than 24 hours after week 24 (when you should be doing kick counts), contact your doctor.
"Can I Travel During Month 5?"
Yes! The 5th month is actually considered one of the safest times to travel during pregnancy. You're past the nausea and fatigue of the first trimester, and you haven't reached the uncomfortable later months yet.
Travel tips:
- Keep flights under 6 hours
- Get up every hour to move around
- Stay hydrated
- Wear compression socks
- Keep your prenatal records with you
- Inform your doctor about your travel plans
"Will My Back Pain Continue to Get Worse?"
For most moms, back pain peaks around the 7th-8th month and then might ease slightly as your body prepares for delivery. However, everyone is different. The good news? Pregnancy-related back pain usually disappears after delivery, sometimes within weeks.
"I'm Craving Weird Food Combinations. Is That Normal?"
Oh yes! Pregnancy cravings are real and scientifically valid. Your changing hormones, nutritional needs, and heightened sense of smell all contribute to wild cravings. Some moms crave ice cream with pickles, others want spicy food all day long. As long as your cravings are safe to eat, enjoy them! Just try to maintain a balanced diet overall. Your baby needs proper nutrition for healthy development.
"How Much Weight Should I Be Gaining?"
By the end of month 5, you should have gained about 12-15 pounds (5-6kgs) from your pre-pregnancy weight. But remember, every body is different. If you started underweight, you might need to gain more. If you started overweight, your doctor might recommend a slower gain. The goal isn't a number—it's a healthy pregnancy. Talk to your doctor about what's right for your individual situation.
What You Need This Month
Comfortable, Flexible Clothing That Grows With You
Your regular clothes are probably getting snug, and it's time to invest in pieces that give you room to grow. However, instead of buying entirely new maternity clothes, consider smart wardrobe additions like a waist band extender. This simple product lets you continue wearing your favorite pre-pregnancy pants and skirts by extending the waistband. It's budget-friendly, practical, and means you're not buying an entirely new wardrobe just for pregnancy. Pair it with loose tops and stretchy fabrics that are comfortable against your growing belly.
High-Waist Belly Support Underwear
Your belly is growing rapidly, and regular underwear might leave marks or feel uncomfortable. High-waist belly support underwear is specifically designed to:
- Provide gentle support to your growing belly
- Prevent underwear marks on sensitive skin
- Keep you comfortable throughout the day
- Offer a smooth, seamless fit under any clothing
The support helps reduce strain on your lower abdomen and can ease some of that round ligament pain we talked about earlier.
Anti-Stretchmark Oil—Start Now!
Anti-stretchmark oil is your best friend during pregnancy. Your skin is stretching rapidly in month 5 as your baby grows, and this is the perfect time to be consistent with prevention.
Why use it:
- Keeps skin hydrated and elastic
- Reduces the appearance of stretch marks (though genetics play a big role)
- Feels nourishing and calming on your skin
- Safe for both you and your baby
When to apply:
- After shower when skin is warm and pores are open
- On your belly, breasts, hips, and thighs (anywhere you're stretching)
- Make it part of your daily self-care ritual—it's 5 minutes of pampering for yourself!
Many moms say this ritual becomes a bonding moment with their baby. Apply the oil, massage your belly gently, and talk to your baby. It's therapeutic for both of you.
Safe Travel Essentials
If you're planning to travel by car during month 5 (which is a great time for pregnancy travel!), there's one product that deserves special attention: the maternity car seat belt adjuster.
Why this matters:
- A regular car seat belt can press directly on your belly and feel uncomfortable
- It can actually be unsafe if it presses on your growing uterus in case of sudden braking
- A maternity car seat belt adjuster positions the belt properly across your hips and shoulder, avoiding your belly entirely
- It's especially important if you're driving long distances
Whether you're traveling to your parents' home or taking a weekend getaway, this small accessory ensures both your comfort and safety on the road.
Stay Hydrated and Nourished
Invest in a good water bottle (a 2-liter one you can track throughout the day) and keep it with you always. Aim for 8-10 glasses of water daily. Your body is working overtime, and proper hydration helps with everything from reducing swelling to supporting your baby's development. Pair this with healthy snacks you can keep handy—nuts, yogurt, fresh fruit, and whole grains. Your baby's brain is developing rapidly, so nutrition is crucial.
Prenatal Vitamins and Supplements
If you haven't already, make sure you're taking prescribed prenatal vitamins. By month 5, your baby's calcium needs are high, so ensure you're getting:
- Iron (for your increased blood volume)
- Calcium (for baby's bones and teeth)
- Folic acid (for continued neural development)
- Omega-3s (for baby's brain development)
Your doctor can recommend the best prenatal supplement for your needs.
Comfortable Footwear
Your feet might start swelling by month 5 (thanks, pregnancy hormones!). Invest in:
- Comfortable, supportive flat shoes
- Sandals or slip-ons for easy wear
- Avoid high heels—they throw off your balance and increase back strain
- Look for shoes with good arch support
Your feet are carrying extra weight now, so be kind to them!
Gender Prediction Myths—What Indian Moms Actually Deal With
Since you can't know your baby's sex from the ultrasound in India, you'll probably hear plenty of "old wives' tales" from family members trying to guess! Let's bust some of these common myths:
"You're carrying high/low, so it's a boy/girl" → Myth
Baby's position depends on your body shape and uterine muscles, not their sex.
"You're craving salty/sweet food, so you're having a boy/girl" → Myth
Cravings are about hormones and nutritional needs, not baby's sex.
"Your skin is glowing/breaking out" → Myth
Skin changes are due to hormones that surge in every pregnancy, regardless of baby's sex.
"Your morning sickness was mild/severe" → Myth
Morning sickness severity varies by individual, not by baby's sex.
"You're carrying a boy/girl because of how you're walking/sitting" → Myth
These old tales have been around for generations, but there's no scientific basis!
The truth? Until your baby is born, no one can know for sure. So smile, nod at people's predictions, and enjoy the mystery! It's actually quite special to have this surprise waiting for you.
Your Wellness Checklist for Month 5
✓ Schedule and attend your 20-week anatomy scan
✓ Start sleeping on your left side
✓ Invest in a good belly support product to ease back pain
✓ Buy comfortable maternity clothes
✓ Drink at least 8-10 glasses of water daily
✓ Practice prenatal yoga or gentle stretching
✓ Keep track of your weight gain with your doctor

The Emotional Side of Month 5
Month 5 is often when pregnancy becomes emotionally "real." You've felt your baby move, seen them on ultrasound, maybe even found out their sex. The abstract concept of "I'm going to be a parent" is slowly becoming concrete.
It's normal to feel:
- Excited and joyful
- Anxious about the future
- Overwhelmed by how much needs to be done
- Emotional (blame the hormones!)
- A beautiful connection to your baby
All of these feelings are valid and normal. Talk to your partner, friends, family, or a therapist about how you're feeling. Pregnancy is as much an emotional journey as it is physical.
Looking Ahead to Month 6
You're officially halfway through your pregnancy! Your baby is now viable outside the womb (though they still need a NICU if born now). In month 6, you'll start feeling stronger, more consistent kicks, and your baby will continue their rapid growth and development. For now, enjoy this golden period of pregnancy. You're doing an amazing job, mama. This is month 5 of the greatest adventure of your life!
