At 40 weeks pregnant, I was so ready to meet my baby, but I also remember feeling like I had reached the final stretch of a marathon. The anticipation was real, and the discomfort was, too. My belly had grown huge, my back hurt constantly, and I had been up for hours, pacing back and forth in the middle of the night. I couldn’t help but wonder, “When is this baby finally going to come?” I was full of excitement, yes, but also frustration and impatience — you know, the typical pregnancy emotions.
I remember thinking, “I’ve made it this far. How much longer?” It can be so overwhelming when your due date arrives, but your baby hasn’t made their grand entrance just yet. If you’re 40 weeks pregnant, you’re likely feeling a lot of the same things. The end is near, but you’re still in the waiting game. I’ve been there, mama, and I’m here to share exactly what to expect at this stage, what signs to watch for, and how to take care of yourself in these final days.
Let’s dive in, because you’ve got this!

1. Your Baby’s Development at 40 Weeks Pregnant
At 40 weeks pregnant, your baby is officially full-term and just about ready to meet the world. Here’s what’s happening with your little one:
Size and Weight
Your baby is roughly the size of a small watermelon, weighing between 6.75 and 10 pounds and measuring about 19 to 21 inches long. Some babies might be a bit smaller or bigger, but they’re getting so close to their birth weight!
Brain and Organ Development
By now, your baby’s organs are fully developed and functioning. Their brain is still making connections, but they’re capable of regulating body functions and adapting to life outside the womb. They’re ready to breathe, digest, and process everything needed for their big debut.
Lung Strength
Your baby’s lungs have fully developed, and they’re producing surfactant — the substance that helps their air sacs stay open once they breathe air after birth. This is crucial for their ability to breathe on their own.
Movement and Reflexes
Your baby has practiced all their reflexes by now, including sucking and grasping. While their movements may feel more restricted as they run out of space, you should still feel regular rolls and wiggles. Make sure to monitor these movements, though, as it’s important to notice any changes or decreases.
2. Changes in Your Body at 40 Weeks Pregnant
As you reach the final weeks of pregnancy, your body is working hard to get ready for labor. Here’s what to expect at 40 weeks:
Pelvic Pressure and “Lightning Crotch”
You may feel more pressure in your pelvis as your baby drops lower. This can make walking uncomfortable, and you might experience sharp, shooting pains (often referred to as “lightning crotch”). It’s normal, though, and just your baby getting into position for labor.
Cervical Changes
At 40 weeks pregnant, your cervix is likely beginning to soften, thin (efface), and dilate. You may even feel cramping or discomfort as your body prepares for labor. If you’ve had a cervical check, you may have been told how many centimeters dilated you are — but don’t worry if things are still progressing slowly. Labor can still happen at any time!
Increased Discomfort
General discomfort, including backaches, fatigue, and difficulty sleeping, can increase as your baby’s size and position change. I remember being so uncomfortable by this point that I couldn’t get a full night’s rest. Make sure to take breaks, rest when you can, and ask for help if you need it.
Nesting Urge
The “nesting instinct” often kicks in during this stage, and you might feel an overwhelming urge to clean, organize, and prepare everything for your baby’s arrival. I definitely felt that — I was scrubbing every corner of my house, folding baby clothes, and setting up the nursery. Just be mindful to pace yourself so you don’t overdo it!
Braxton Hicks Contractions
These “practice contractions” may become more frequent and intense as you approach labor. They’re usually irregular and go away when you change positions, but they’re still your body’s way of preparing for the real thing. If they become consistent or painful, however, be sure to call your doctor to rule out early labor.
3. Tips for Staying Comfortable at 40 Weeks Pregnant
At 40 weeks pregnant, it can be tough to feel comfortable, but there are a few things you can do to help manage discomfort and stay sane during the final stretch:
Get Plenty of Rest
I know it’s hard when you’re so uncomfortable, but try to take naps or at least rest throughout the day. Your body needs energy for labor, and getting extra rest now will help you when it’s time to push. Don’t feel guilty about it — your body is working overtime, so give yourself grace.
Use a Pregnancy Pillow
If you’re struggling to find a comfortable sleeping position, a pregnancy pillow can make a huge difference. I loved mine! It provided extra support for my belly, hips, and back, and helped me sleep more comfortably (even if it wasn’t a full night’s rest).
Stay Hydrated
Drinking plenty of water is key to staying comfortable. Hydration helps reduce swelling and keeps things moving in your body. It’s also important for your baby’s health, so drink up!
Take Gentle Walks
Gentle movement like walking can help with circulation and reduce swelling, plus it can help relieve pressure in your lower back and pelvis. I went for short walks every day to keep my body moving and prevent stiffness.
Relax with a Warm Bath
A warm bath can help relieve sore muscles, reduce swelling, and calm your mind. Just be sure the water isn’t too hot, and add some Epsom salts to help relax your muscles. It was one of my go-to tricks to ease the discomfort.
4. What to Do at 40 Weeks Pregnant?
At this stage, it’s time to get ready for your baby’s arrival. Here’s what you should focus on:
Prepare Your Hospital Bag
If you haven’t packed your hospital bag yet, now’s the time. Make sure you have everything you’ll need for yourself, your partner, and your baby. Don’t forget the essentials like comfortable clothes, toiletries, and a baby blanket. And double-check that your car seat is properly installed!
Monitor Contractions
Start paying attention to whether your contractions are true labor contractions or just Braxton Hicks. If you’re experiencing regular, painful contractions, or if you have any of the other signs of labor (like your water breaking or a significant loss of mucus plug), call your healthcare provider.
Track Baby’s Movements
At 40 weeks, your baby’s movements may feel different as they have less space, but it’s still important to monitor their activity. You should still feel consistent rolls, wiggles, and kicks. If you notice any decrease in movement, contact your doctor immediately.
Relax and Prepare Mentally
While it’s easy to get caught up in the hustle of getting everything ready, don’t forget to take time to mentally prepare. Relax, breathe, and enjoy the final days of your pregnancy. You’ve got this, and soon you’ll be holding your sweet baby in your arms!
5. Expert Insight : What the Experts Say?
According to The American College of Obstetricians and Gynecologists (ACOG), a full-term pregnancy is considered to be between 39 and 40 weeks. At 40 weeks, your baby is fully developed and ready to be born, but it’s still common to go past your due date, especially for first-time moms. If labor hasn’t started by 41-42 weeks, your doctor may discuss induction options.
6. Wrapping Up with Love & Support
Mama, you’ve made it! The final stretch is here, and while it’s not always easy, you are doing an incredible job. You’re about to meet your baby — the little one you’ve carried for so long — and soon, the discomfort will be a distant memory.
