38 Weeks Pregnant: What to Expect, What’s Normal, and What’s Next

Here’s what nobody tells you about week 38: you’re in the final stretch, but your body isn’t done yet. Most people think “38 weeks pregnant” means you’re ready to go — but medically, those last two weeks matter more than you’d expect.

At 38 weeks pregnant, your baby is nearly full-size, your lungs are working overtime, and every contraction might feel like the real thing. This guide breaks down what’s actually happening in your body, which symptoms are normal (and which aren’t), how to spot real labor versus false alarms, and what to do with the anxiety that comes with counting down to due date.

What’s Happening at 38 Weeks Pregnant

Your body has been doing something extraordinary for nearly ten months. And right now, in these final weeks, it’s still working hard — even when all you feel is exhausted and ready.

Most babies are head-down by now, settled low into your pelvis. That pressure you’re feeling? That’s your baby literally getting into position. It’s uncomfortable, but it’s a good sign.

Size-wise, your baby is roughly the size of a leek — somewhere around 6.5 to 7 pounds and about 19 to 20 inches long. They’re filling out, gaining the fat stores they’ll need once they’re earthside.

Here’s what matters most right now: the lungs. They’re one of the last organs to fully mature, and by 38 weeks, they’re producing surfactant — the substance that helps them inflate and breathe on their own after birth. The AAP notes that babies born at 39 weeks or later have better outcomes for lung function and feeding, which is part of why most providers prefer to wait for labor to begin naturally unless there’s a medical reason not to.

Your body is changing fast too. You might notice your bump sitting lower, more pelvic pressure, increased discharge, and the famous “lightning crotch.” Braxton Hicks contractions can pick up intensity. Some women start losing their mucus plug around now.

If you haven’t already, it’s worth getting clear on the stages of labor and dilation — knowing what early labor actually feels like helps you stay calm when things start moving.

You’re almost there. Your body knows what it’s doing, even on the days it doesn’t feel that way.

Common Symptoms and Physical Changes at 38 Weeks

Here’s the honest truth: the last few weeks are hard. Not “cute pregnancy glow” hard — genuinely, physically uncomfortable hard.

Braxton Hicks contractions can feel surprisingly intense right now. They’re your uterus practicing, and they’re real. They don’t mean labor is starting, but they do mean your body is working.

Pelvic pressure is another one nobody warns you about enough. When your baby drops lower, it can feel like you’re carrying a bowling ball between your legs. Walking slowly, sitting down carefully, wincing getting out of the car — all completely normal at 38 weeks pregnant.

Sleep is probably a mess. You can’t get comfortable, you’re up to pee every two hours, and your brain won’t stop making lists. This is one of those things where there’s no perfect fix — just permission to rest whenever you actually can, even if it’s not “real” sleep.

Mood shifts are real too. One hour you feel ready. The next you feel terrified. Both are completely valid. If anxiety is sitting heavy, it’s worth paying attention to — postpartum anxiety symptoms can actually start before birth, and knowing what to watch for matters.

On the baby’s side: The AAP notes that babies born at 38 weeks are considered early term, and those final two weeks of pregnancy support important brain, lung, and liver development — so as uncomfortable as the waiting is, your body is still doing meaningful work.

Swollen feet, trouble breathing deeply, constant heartburn — these aren’t you being dramatic. They’re just the final stretch doing its thing. You’re not broken. You’re almost done.

Signs Labor Might Be Starting (vs. False Alarms)

Here’s the thing nobody warns you about: your body will do a lot of convincing practice runs before the real thing starts. It can mess with your head, especially when you’re exhausted and just ready.

Braxton-Hicks contractions are your uterus rehearsing. They feel tight, sometimes uncomfortable, but they’re usually irregular — they don’t get longer, stronger, or closer together. Drink some water, change positions, and they typically ease off.

Prodromal labor is harder. It feels more like real labor — contractions that have a rhythm, maybe even a pattern. But then they stall. They don’t progress. This can go on for days, and it is exhausting in a way that’s hard to explain to someone who hasn’t felt it.

True early labor has a different quality. Contractions keep coming. They get more intense over time. Changing positions doesn’t stop them. That’s the key difference — real contractions have momentum.

Other signs worth paying attention to: your mucus plug releasing (can look like thick, sometimes bloody discharge), your water breaking (which might be a gush or a slow trickle), or a deep, low backache that won’t quit.

If you’re around 38 weeks pregnant and things feel different — not just uncomfortable, but different — trust that. You know your body.

A good rule of thumb most providers use is the 5-1-1 pattern: contractions five minutes apart, lasting one minute each, for at least one hour. That’s usually when it’s time to call. For a fuller breakdown of what to watch for, the Onzenna guide on when to go to hospital during labor walks through the timeline clearly.

And if you’re ever unsure? Call your provider anyway. That’s what they’re there for. You don’t need to be certain before you pick up the phone.

Your Prenatal Care and Monitoring at 38 Weeks

By now, appointments feel like a part-time job. And honestly? That’s a good thing — even when you’re exhausted and just want to be done.

At 38 weeks pregnant, you’re likely seeing your provider every single week. These visits are short, but they matter. Your provider is watching for changes that tell them how close you are and how you and baby are doing.

Cervical checks often start around now. They’re optional — you can decline — but they give your provider a sense of whether your cervix is softening, thinning (effacing), or starting to open (dilating). They’re uncomfortable. They’re not always predictive. But they’re one piece of the picture.

If you haven’t been tested for Group B Strep yet, it typically happens between 36 and 38 weeks. It’s a simple swab. If you test positive, you’ll receive IV antibiotics during labor — The AAP recommends this as standard care to significantly reduce the risk of passing the infection to your baby at birth.

Some providers also order a non-stress test (NST) at this stage, especially if you have any risk factors — like gestational hypertension, a smaller baby, or a pregnancy that’s gone past your due date. An NST just monitors baby’s heart rate and movement for about 20 minutes. It’s low-key, but it’s reassuring.

If monitoring does become more frequent, try not to spiral. It usually means your provider wants more information — not that something is wrong.

This is also a good time to revisit your birth preferences with your care team if you haven’t already. And if you’re thinking about who you want in that room with you, the Onzenna guide on what is a doula is worth a read before your next appointment.

You’re close. Keep showing up.

Preparing for Labor: What You Can Do Now

Here’s the thing nobody tells you: being 38 weeks pregnant and “ready” are two completely different things. You can feel completely done with pregnancy and still feel completely unprepared for what comes next. Both things are true, and that’s okay.

Start with your birth plan. Keep it simple — one page, clear preferences, flexible language. Your care team will appreciate it, and having it written down helps you feel less like things are happening to you.

Your hospital bag should already be by the door. If it’s not, do it today. Pack for you first: a comfortable robe, your own pillow, snacks for labor, lip balm (you will want it), and whatever helps you feel like yourself. If your partner is coming, point them toward the hospital bag checklist for dad — it’s one less thing for you to manage.

For anxiety, I’m not going to tell you to just breathe. But I will tell you that the anxiety usually isn’t about labor itself — it’s about the unknown. Write down your specific fears. Name them. They’re easier to carry when they’re not just swirling.

For positioning, walking and sitting upright genuinely help move baby into a good place. Hands-and-knees stretches can ease pressure and encourage optimal positioning too. Nothing fancy required.

If you haven’t already, think about delayed cord clamping — it’s worth reading about before you’re in the room and someone’s asking. Our piece on delayed cord clamping breaks it down simply so you can decide what you want.

You don’t have to feel ready. You just have to show up. That part, you’ve already been doing for nine months.

When to Call Your Provider: Red Flags at 38 Weeks

Here’s the thing nobody wants to say out loud: most of what you feel at 38 weeks is just… a lot. Pressure, cramping, exhaustion, the whole circus. But some things are not “just pregnancy,” and you need to know the difference.

Call your provider immediately if you have any vaginal bleeding that’s more than light spotting. Not tomorrow. Not after you Google it. Now.

If you think your water has broken — even if you’re not sure, even if it seems like a slow trickle — call. Fluid leaking from your vagina needs to be evaluated right away, because once membranes rupture, the clock matters.

Decreased fetal movement is one I take seriously. The AAP recommends that pregnant women who notice a significant decrease in fetal movement contact their care provider promptly for evaluation rather than waiting to see if it picks up on its own. Trust that instinct. If something feels off, say something.

Severe or sudden abdominal pain — not the usual tightening, but sharp, constant, or one-sided pain — is a reason to call. Same with a headache that won’t go away, vision changes, or sudden swelling in your face and hands. Those can be signs of preeclampsia, which can escalate fast.

Fever over 100.4°F. Painful or burning urination. Any sign of infection matters more right now than it would have earlier in pregnancy.

You are not being dramatic. You are not wasting anyone’s time. Providers would genuinely rather hear from you at 2am and tell you everything’s fine than have you wait.

If you’ve been keeping up with your care since your first ob appointment what to expect, you already know your provider’s after-hours line. Keep it in your phone. Use it.

Managing Anxiety and Staying Grounded in the Final Days

Nobody tells you how strange the waiting feels. You’ve done everything right, the bag is packed, and still — your brain won’t quiet down.

That anxiety isn’t weakness. It’s your nervous system doing exactly what it’s supposed to do before something enormous happens. Being 38 weeks pregnant and feeling on edge is not a sign something is wrong. It’s a sign you’re paying attention.

Here’s what I know: the feelings don’t have to make sense. You can be excited and terrified in the same breath. You can cry because you’re going to miss being pregnant. You can cry because you cannot wait for it to be over. Both are true. Neither cancels the other out.

When the spiral starts, get out of your head and into your body. Not a workout — just movement. A slow walk. Hands in warm water. Feet on the floor. Something physical that reminds you that you are here and you are okay right now.

Limit the rabbit holes. Googling symptoms at midnight will not help you. It will not prepare you. It will only feed the anxiety that’s already working overtime.

Talk to someone who has been through it — not for advice, just to feel less alone. There is something that settles in you when another woman looks at you and says, “I know. It’s a lot.”

Write things down if your thoughts won’t stop racing. Not a to-do list. Just whatever is in your head. Getting it out of your body and onto paper can quiet things more than you’d expect.

And give yourself permission to do absolutely nothing. To sit. To rest. To let this last stretch be what it is — uncomfortable, tender, and completely valid.

You are not behind. You are not failing. You are almost there.

Frequently Asked Questions

Is 38 weeks considered full term, and when can baby arrive?

At 38 weeks, you’re technically in the “early term” window — babies born now are considered early term, while 39 weeks and beyond is full term. Your baby’s organs (especially lungs and liver) are still maturing, which is why providers often recommend waiting for labor to start naturally unless there’s a medical reason to deliver earlier.

What’s the difference between Braxton-Hicks contractions and real labor contractions at 38 weeks?

Braxton-Hicks are usually irregular, painless or mildly uncomfortable, and stop when you move or change position. Real labor contractions get progressively closer together, stronger, and more painful, and they continue regardless of what you’re doing. If you’re unsure, call your provider — that’s what they’re there for.

Is it safe to have sex or use natural induction methods at 38 weeks pregnant?

Sex is generally safe at 38 weeks unless your provider has told you otherwise (like if you have placenta previa or your water has broken). As for natural induction methods, some have minimal evidence and others carry real risks — always check with your provider before trying anything, especially at this stage.

What should I do if my baby hasn’t dropped or engaged by 38 weeks?

Not all babies drop at the same time, and some don’t fully engage until labor begins. At your next appointment, ask your provider about baby’s position and station — they can assess whether anything needs monitoring and help you understand what to expect.

How often should I feel baby move at 38 weeks, and what counts as decreased movement?

You should still feel your baby move regularly — most providers recommend counting at least 10 movements in a 2-hour period. If you notice a real change in your baby’s normal pattern, call your provider immediately. Trust your instinct: you know your baby’s baseline better than anyone.
