Pregnancy Trimester Week by Week

Weeks? Months? Trimesters? Stages of Pregnancy 04 Weeks to 40 Weeks

Pregnancy lasts about 40 weeks, counting from the first day of your last normal period. The weeks are grouped into three trimesters. Find out what’s happening with you and your baby in these three stages.

4 Weeks Pregnant

Here’s what’s happening during Week 4 of your pregnancy.

Week 4: Positive test: You’re pregnant! You may be starting to feel bloated, crampy, tired and moody, and experiencing sore breasts, nausea/vomiting and a frequent need to pee. But don’t worry if you’re not, that’s normal.

What to do now:
– Invest in an extra supportive bra, especially if your breasts are expanding. Many women grow a full cup size in the first few weeks.
– Avoid chemicals and secondhand smoke. Ask your partner to take over the litterbox duties (cat feces may harbor parasites that cause toxoplasmosis, an infection that can harm the fetus) and to pump the gas in your car.

Your Growing Baby:

The fertilized egg (known as a zygote) implants in the wall of the uterus; the placenta and umbilical cord begin to form.

Your Growing Belly:

The fertilized egg burrowing into your uterus can make you shed a few spots of blood. Any pregnancy symptoms you have will be bare, if at all, noticeable. If you’re very sensitive, you may notice feelings of fatigue, queasiness, bloating, and breast tenderness, and changes in your skin and hair. If you take a super-sensitive test, such as a blood test at your doctor’s office, it’s possible to get a positive result a week after conception. If you test at home this early, know that it’s possible to get a false negative at this stage.

Tips & To-Do’s:

Too Early To Test?

During the first few weeks, your body is working 24/7 behind the scenes to support the pregnancy, and fatigue is a normal response. When the fertilized egg implants into the plush lining of the uterus about six to 12 days after conception, spotting—light vaginal bleeding—may occur. Your breasts may be extra tender as early as a week or two after conception. Here are nine subtle clues that you might be pregnant.

Things to think about this week

Sure, what you eat during pregnancy is vital, but that doesn’t mean you have to be afraid of everything you put in your mouth or force yourself to eat foods you don’t like. Simply stick to these 10 basics do’s and don’ts.

9 Weeks Pregnant

Here’s what’s happening during Week 9 of your pregnancy.

Week 9: The pressure of your growing uterus on your bladder may cause you to leak small amounts of urine.

What to do now:
– Start doing Kegels: Squeeze the muscles around your vagina as if you’re stopping the flow of urine; do several at a time, a few times a day throughout pregnancy. They strengthen your pelvic-floor muscles, helping with incontinence while preparing your body for delivery.

Your Growing Baby:

The heart is almost completely developed. Eyelids are forming, as are hair follicles and nipples; the embryo can hiccup now. Fingers and toes are no longer webbed. The arms develop bones, and the hands begin to touch the face. The legs start to move. Length: about 3/4 inch.

Your Growing Belly:

Your nauseating hCG levels are at their peak this week. The good news is that starting next week, as your hormone levels stabilize, you’ll start feeling a lot better. The bad news is that this week is probably going to be rough. If you’re throwing up a lot, drink plenty of water to keep yourself from dehydrating. Your uterus has doubled in size and is now about the size of a tennis ball. The area under your navel is definitely firmer than usual.

Most women report being uninterested in sex at this stage, though some women also report being more interested than usual. You may begin to notice changes to your hair and skin. Your hair might feel thick and lustrous–or greasy, thin, and limp.

You probably don’t feel like exercising much this week, but do try to take walks– they’ll help your food move on down.

13 Weeks Pregnant

Here’s what’s happening during Week 13 of your pregnancy.

Week 13: Now that you’ve finished your first trimester, you can start eating for two—a little. Plan on gaining about 12 pounds during the next 14 or so weeks.

What to do now:
– To support your baby’s growth without gaining too much weight, aim to get 300 extra calories a day from healthy foods.
– Start shopping for maternity clothes. Many shops have belly bumps to mimic your girth in later pregnancy.

Your Growing Baby:

The nose and lips are completely formed, and the fetus begins to produce and excrete urine.

Your baby is 2 1/2 to 3 inches long, the size of a medium goldfish. She weighs about one ounce. Your baby is shorter than a finger, but her face is already showing individual features and characteristics. Your baby spends her time in your womb flexing her new and developing muscles and joints. Bouts of prenatal hiccups are strengthening your baby’s diaphragm, which is preparing her respiratory system for breathing. Less glamorous but highly necessary organ systems for making hormones, absorbing nutrients, and filtering waste are also in place this week. The pancreas, gallbladder, and thyroid have developed, the kidneys can make urine, and her bone marrow is making white blood cells to help fight infection after she’s born.

Your Growing Belly:

Good news—by week 13, you’ll have more energy and less nausea (it could be gone entirely by weeks 14 to 15), as the placenta takes over hormone production. Your smell and taste aversions will probably stick with you for the rest of your pregnancy, but unless you’re very unlucky, the spontaneous throwing up will ease. If you’re starting to feel better, this could be a good time to try a new exercise. If you haven’t tried swimming lately, check out why many care providers call it the perfect pregnancy exercise. Yoga is another low-impact activity that can help you feel better. Choose an establishment that offers a specialized prenatal yoga class. Feel calm, centered and prepared for labor with these safe yoga poses >>

Tips & To-Do’s:

Water Baby

When you do exercises in water, your abdominal muscles are engaged and lengthened because they’re working to keep you balanced. And the buoyancy of the water makes it easier to hold poses—such as yoga’s Warrior III—that you might not be able to hold as well on land, providing you with more toning benefits and enabling deeper stretches. Ease pregnancy discomforts and stay in shape safely with this cool pool workout.

Things to think about this week

Now that you’re entering your second trimester (it starts next week), you’ll want to make the most of your renewed energy, mobility and good mood to prepare for giving birth. Your first step should be to sign up for a childbirth education course. Here’s a rundown of the most common childbirth classes.

18 Weeks Pregnant

Your baby measures about 14cm this week – roughly the same as a bell pepper!

Time to switch things up. Starting around 18 weeks pregnant you should begin to sleep on your side instead of your back. That’s because the baby (and your uterus) is getting big enough to press against large veins in the back of your abdomen, which can reduce the amount of blood going to your heart, making you feel lightheaded—or worse, lowering your blood pressure. Sounds scary, but it’s totally preventable by simply sleeping on your side. Of course, your veins aren’t the only things that are prone to pressure—you are too! At pregnancy week 18, there’s a lot going on. Be sure, in your hectic schedule, that you plan some time to take breaks and unwind. Great excuse for a date night or a prenatal massage!

18 Weeks Pregnant Is How Many Months?

At 18 weeks, you’re officially four months pregnant. Only five more months to go!

How Big Is Baby at 18 Weeks?

At 18 weeks pregnant, a baby is as big as an artichoke. Baby’s about 5.6 inches long and about 6.7 ounces now and keeps growing quickly. That’s why you’re probably feeling so hungry!


Not only are you super busy preparing for baby, but you might be having some not-so-fun 18 weeks pregnant symptoms, like swollen feet or hands, backaches, leg cramps, and nosebleeds. And the stress and discomfort can keep you up at night around week 18 of pregnancy. Here’s the scoop on the 18 weeks pregnant symptoms you may be feeling:

Swollen feet and/or hands. Swelling can be an annoying pregnancy symptom. It’s nothing to worry about as long as the swelling isn’t sudden or severe. If it is, tell your doctor right away.

Backaches. Baby’s putting a lot of pressure on your insides, causing aches and pains in your back.

Leg cramps. Cramps can be a sign of dehydration, so drink up!

Varicose veins. These visible purple or blue veins are swollen due to all that extra pressure on your circulatory system. To deal with them, change positions often, prop your legs up when you can, get plenty of exercise, and avoid tight clothes and shoes.

Trouble sleeping. Your mind is working overtime and you’re getting more and more uncomfortable. This can wreak havoc on your ability to catch the Zs you need.

Nosebleeds. Bet you never expected these! Increased pressure on the veins in your nose may be making it bleed more than usual. If you have a nosebleed, apply pressure by pinching your nose for five to ten minutes. An ice pack can also help stop the bleeding.

Baby kicks. Whether you’re 18 weeks pregnant with twins, triplets, or a single baby, you’re probably feeling not just tiny flutters but more definitive sensations resembling actual kicks. They’re getting stronger!


Your 18 weeks pregnant belly is rapidly expanding—all the stretching and pressure it’s causing are what’s causing those symptoms.

Weight gain at 18 weeks pregnant is recommended to be about 1 to 2 pounds per week for women of average BMI, whether you’re having one baby or you’re 18 weeks pregnant with twins. Let your doctor know if you have any concerns with your weight gain so far. Drastic or sudden weight gain or weight loss could be signs of a problem.

If you’re 18 weeks pregnant and not showing much, everything’s probably A-OK. Remember: Every pregnant body is different, and your uterus will grow up and out of your pelvis at a slightly different time as another pregnant woman’s does.


What the heck is baby doing inside your 18 weeks pregnant belly? A lot! Your 18- week fetus is working his or her muscles and practicing all kinds of moves. Can you believe baby’s yawning, hiccupping, sucking, and swallowing? He or she is twisting, rolling, punching, and kicking too—and is big enough that you might be able to feel him or her doing it!

If you’re 18 weeks pregnant with twins, there’s a membrane that separates your two 18-week fetuses. As they wiggle around in there, they’ll push fluid around and the membrane will shift slightly—you’d probably be able to see that on an 18 weeks pregnant ultrasound.

At 18 weeks pregnant, the big ultrasound is on your calendar for sometime in the next few weeks. The mid-pregnancy ultrasound (a.k.a. anatomy scan or level-two ultrasound) is a detailed examination of baby’s entire body. It’s a pretty cool peek inside! Your 18-week fetus will be measured to make sure growth is on track. Major organs will be checked for proper development. And amniotic fluid, placenta location, and fetal heart rate will all be examined as well, to be sure baby’s thriving.

For moms-to-be who are 18-weeks pregnant with twins (or other multiples), both (or all) babies’ anatomy will be scanned at one appointment.

If you want to know whether you’re having a boy or girl, the technician will be able to tell you with about 95 percent certainty at the mid-pregnancy ultrasound—as long as baby moves into a position where his or her organs are visible. Some babies don’t exactly cooperate!

13 Weeks Pregnant

Your baby now weighs around one pound. From around now, they start to weigh more than the placenta. They’re about the size of a bag of sugar.

It’s getting crowded in there! Now that you’re 22 weeks pregnant, your rapidly growing baby is invading your space—to say the least. That’s why it might be tough to catch your breath and why your back might be killing you. Hey, as baby grows, he or she may be expanding your belly so much (so fast) at week 22 of pregnancy that you might start to get some stretch marks (sorry)—and you might even have a newfound “outtie”! While you might not love all these side effects, you’ll probably want to capture your pregnant belly in some professional photos. 22 weeks is a good time to schedule a maternity portrait session. You’ll want to aim for a third trimester sesh to capture that big, beautiful belly, but it shouldn’t be so late that you risk going into labor before your appointment.

How Big Is Baby at 22 Weeks?

At 22 weeks, baby is the size of a coconut. Average baby size at 22 weeks is 10.9 inches long (from the crown of the head to the heel of the foot) and 15.2 ounces.

22 Weeks Pregnant Is How Many Months?

Hmm… it’s becoming difficult to keep track, so what exactly is 22 weeks in months you ask? Answer is… you’re four months and about four weeks pregnant. Once week 22 of pregnancy ends, you’ll officially be five months pregnant.


The most common 22 weeks pregnant symptoms have to do with the fact that your baby (or babies, if you’re 22 weeks pregnant with twins) is taking over so much territory in your bod. This includes:

  • Stretch marks. These scars are caused when your skin stretches so fast or so much that it actually tears below the surface. What’s not so cool is that the stretch marks may never go away completely, but they will fade in color after delivery, so they’ll be much less noticeable.
  • Outtie belly button. Your innie has basically gone inside out and you’ve suddenly got an outtie. This is another byproduct of an expanding belly. It can be a weird feeling, we know. Your outtie will go back to an innie, we promise!
  • Increased sex drive. Some moms-to-be actually find they have an increase in libido around 22 weeks. That’s because your hormones are pretty much raging at this point. (We hope you’re enjoying it!)
  • Increased vaginal discharge. You’ve got a water works situation down there—SO not fun, but don’t worry, it’s just the result of increased blood flow down there. This could be a reason not to feel the sex drive boost other moms-to-be get at this phase of the game, but we think you should try to get into the mood anyhow. We really doubt your partner will mind a little excess… um… lubrication.
  • Swollen hands and/or feet. Now that you’re pregnant, you have an increase in the amount of fluids in your body. So minor swelling is totally normal and will die down pretty much as soon as baby is born. Severe or sudden swelling, on the other hand, is not normal. It could be a sign of a dangerous pregnancy complication called preeclampsia, so tell your OB right away if you’re super swollen or swollen with sudden onset.
  • Backaches. Your back hurts due to extra pressure from baby and from carrying around the extra weight. A heating pad, a prenatal massage, and/or sleeping with a body pillow can help ease the pain.
  • Hair growth. This is a pretty great symptom when the hair is… Actually. On. Your. Head. When it’s not on your head, well, go ahead and curse those hormones for the umpteenth time. (And break out the tweezers if you want!)
  • Trouble catching your breath. Baby continues to crowd your lungs, making it tough to breathe at times. Remember not to take your workouts too far, and when you feel winded, take a break right away.


A typical 22 weeks pregnant belly measures approximately 20 to 24 centimeters from pelvic bone to the top of the uterus—that’s called the “fundal height.” If you’re 22 weeks pregnant with twins, don’t even consider fundal height, since twin pregnancies are all so different, there’s no real “typical.”

At 22 weeks pregnant, weight gain is likely on your mind. Your OB is probably telling you to stick to a slow and steady weight gain—about a pound or slightly more or less per week, depending on your body type. To do that, many people advise eating about 300 extra calories per day. Don’t obsess over calorie counting or anything—it’s just a good guideline to keep in mind.

27 Weeks Pregnant

Your baby’s about the size of a cauliflower now.

Biomedical illustration of week 27 in development when the fetus weighs almost 2 pounds and is about 14.5 inches long, and the eyes can blink. Series.

Raise your sparkling water glass and say goodbye to the second trimester! At 27 weeks, baby is breathing (it’s amniotic fluid, not air, but still pretty cool) and even showing brain activity. You’ve got a lot on your brain, too, from wondering what the birth is going to be like to trying to find the best pediatrician for baby. As you look ahead to the third trimester, be prepared for some pretty embarrassing stuff (like having to pee all the time—and maybe even when you don’t mean to!). It’s all par for the late-pregnancy course and totally temporary. It’s time to head down the home stretch. Are you ready?

How Big Is Baby at 27 Weeks?

At 27 weeks pregnant, baby is as big as a head of lettuce. The average 27-week fetus measures 14.4 inches and weighs 1.9 pounds. But baby’s not just getting bigger—he or she is also getting smarter.

27 Weeks Pregnant Is How Many Months?

27 weeks pregnant is five months and four weeks pregnant. This is the last week of the sixth month and the last week of the second trimester.


The annoying symptoms you’ve been having aren’t likely to go away anytime soon, but at least you’ve probably found some ways to deal with them—and hey, maybe you’re even used to them right now. The most common 27 weeks pregnant symptoms are:

  • Leg cramps. Keep stretching those legs—flexing your feet can help—and drinking lots of water to prevent these ouchies.
  • Backaches. Gentle stretching can help your back, too. Consider sleeping with one of those huge body pillows, which can ease some of the pressure on your hips and help you get into a comfy position for your back.
  • Constipation. If you’re stopped up and you’ve done all the usual prevention—eaten lots of fibrous foods, drank lots of water, and taken plenty of walks—ask your doctor if a fiber supplement or stool softener is safe to take.
  • Hemorrhoids. Straining to go to the bathroom and all the pressure baby’s putting on your lower half can cause this not-so-pretty 27 weeks pregnancy symptom.
  • Skin, hair, and nail changes. Notch this one into the unpredictable pregnancy symptom category. Your skin, hair, and nails might be thicker or grow faster (yay!) but they might also be more brittle (boo).
  • Snissing. This is what we call peeing when you sneeze. Baby is putting a ton of pressure on your bladder and there’s not much you can do about it except take frequent pit stops to empty your bladder and maybe wear a pantiliner if you’re worried about an unexpected achoo.

Women who are 27 weeks pregnant with twins are vulnerable to preterm labor, so if you notice any pregnancy symptoms that are out of the ordinary—such as bleeding, watery discharge, abdominal pains, or consistent, repeated contractions, tell your OB right away.


Healthy weight gain at 27 weeks pregnant is around 15 to 30 pounds. If you’ve gained more quickly than recommended—two or more pounds per week—your OB may tell you to slow it down a bit. Sounds rough, but she can give you some tips on keeping the weight gain under control. By sticking to pregnancy weight gain recommendations, you’re reducing your risk of pregnancy complications and preterm labor. You’re also making your third trimester a little easier by not having extra pounds to carry around town with you.

If you’re 27 weeks pregnant with twins, you’ve probably gained more weight—about 29 to 44 pounds. Still, your twins are growing and developing at about the same rate as singleton babies do—though one baby is probably a bit smaller than the other.

You’re probably feeling a ton of kicks inside that 27 weeks pregnant belly—twice as many if you’re 27 weeks pregnant with twins. You may even feel tiny hiccups, which are like patterns of little twitches. For now, sit back and enjoy the kicks and jabs. Next week, you should start counting kicks to make sure baby seems consistently active from day to day.

300 extra calories doesn’t mean you have to eat exactly three meals, plus one or two small snacks. In fact, you should consider switching it up and eating five or six small meals over the course of your day. That way, it might be easier to stick to a well-rounded diet (since, admit it, most of us make healthier choices with our meals than we do with our snacks). Plus, by eating smaller meals and more regularly, you’ll lower your chances of having drops in energy, or heartburn, indigestion, and other issues with that 22-week pregnant belly. Sounds delicious to us!

31 weeks pregnant

Your baby is now about the size of a coconut!e

Can you believe all five of baby’s senses are fully developed at 31 weeks pregnant? Baby’s also getting smarter! In the meantime, you might actually feel a little… dumb. You’re not! It’s just that many moms-to-be find themselves acting absentmindedly during the third trimester. Some say that “pregnancy brain” isn’t a real thing, but can you honestly think of another time in your life when you’ve had as much on your mind as now? We’re guessing no. That right there is enough of a reason to be so forgetful at week 31 of pregnancy.

How Big Is Baby at 31 Weeks?

At 31 weeks pregnant, baby is as big as a bunch of asparagus. Baby’s about 16.2 inches long and weighs about 3.3 pounds. Baby’s getting so big, he or she’s probably crowding your lungs, which is why you might find yourself winded on a normal walk up the stairs.

31 Weeks Pregnant Is How Many Months?

31 weeks pregnant is six months and three weeks pregnant. You’re wrapping up month seven at the end of this week.


From week 31 of pregnancy on, you’re bound to feel a lot of the same symptoms you’ve already been experiencing. Some may get worse, and some may become bearable. Here are the most typical 31 weeks pregnant symptoms:

  • Shortness of breath. You might start to have more trouble getting around as you get heavier and more short of breath. Remember not to push yourself too much. It’s good for you and baby to get some exercise, but definitely take breaks to rest as much as you need to.
  • Dry, brittle nails. Sure, you’re having extra finger- and toenail growth, but that can make those nails feel dry and easily broken. Some moms-to-be have success with a moisturizing cuticle oil. This may also be the perfect excuse for a spa mani-pedi.
  • Braxton Hicks contractions. To ease the discomfort of Braxton Hicks, drink plenty of water and change positions often. This will prevent those “practice contractions” from turning into preterm labor. If you have certain pregnancy complications, or if you’re 31 weeks pregnant with twins, you’re at higher risk for preterm labor.
  • Leaky boobs. That yellow liquid is baby’s first food, called colostrum, and your body’s getting it ready for the big arrival.
  • Frequent urination. Your bladder’s just as crowded as your lungs are. Not much you can do about it except mentally plan more bathroom breaks into your daily routine.
  • Backaches. Be sure to keep stretching to ease your aching back. That prenatal yoga class can help!

Trouble sleeping. It’s no wonder you can’t sleep when your back hurts, your belly’s contracting, you can’t find a comfortable position, oh—and you have to keep getting up to pee!


By 31 weeks pregnant you’ve probably gained about 21 to 27 pounds. If you’re 31 weeks pregnant with twins, it’s more like 27 to 42 pounds.

Your 31 weeks pregnant belly is getting in the way of everyday things like tying your shoes and sex. It’s even in the way of your usual swagger—have you started waddling yet?!

36 weeks pregnant

Your baby weighs an impressive 6 pounds (2.7kg) – give or take – and is about the size of a large cabbage.

It’s month 9 already? Time is flying! Since baby really could decide to arrive any day now, try to put in your final prep work at 36 weeks pregnant. For example, if you took a childbirth class a few months ago, re-read the materials you were given and practice the breathing techniques you learned with your partner. Go over your plan for getting to the hospital and all the what-ifs. Update your boss and colleagues of the status of all your work projects so they know where to take over if you’re suddenly out of the office. Week 36 of pregnancy is also a good time to enjoy a date with your partner. We’re guessing you won’t be up for dancing, but how about a nice dinner?

How Big Is Baby at 36 Weeks?

At 36 weeks pregnant, baby is as big as a papaya, measuring about 18.7 inches from crown to heel and weighing in around 5.8 pounds.

36 Weeks Pregnant Is How Many Months?

36 weeks is eight months pregnant. Welcome to the first week of month 9! You’re just four weeks away from your due date.


When you have just four weeks to go, pretty much all your symptoms have to do with the fact that baby’s almost here. Your 36 weeks pregnant symptoms may include:

  • Better ability to breathe. As baby descends into your pelvis, your lungs will have more space, and you’ll be able to breathe more deeply.
  • Pelvic discomfort. You’re feeling this one for the same reason you can breathe again! Baby’s down low, putting pressure on your pelvis. Look out for signs of labor though, including regular, persistent contractions.
  • Trouble sleeping. Finding yourself up at 3 a.m. writing thank-you notes or reorganizing the closet? We’ve been there! Find some ways to relax even if you aren’t getting much shut-eye.
  • Heartburn. Your growing baby is crowding your digestive system, preventing it from working the way it did when you weren’t pregnant. Antacids can help (as long as your doctor has okayed them). Prevent heartburn as much as you can by avoiding citrusy, spicy, vinegary, and greasy foods. (No fun, we know, but it’s worth avoiding the pain.)
  • Swollen ankles and feet. Minor swelling is totally normal at 36 weeks pregnant and you’re even more likely to have it if you’re 36 weeks pregnant with twins. You might find that almost as soon as you deliver your baby, it completely disappears. Seriously! But severe or sudden swelling can be a sign of a serious problem, so let your doctor know ASAP.
  • Changes in vaginal discharge. At 36 weeks pregnant, discharge may increase as your body readies itself for birth. But look out for watery discharge (which could be amniotic fluid—call your doctor!), blood (a sign of preterm labor), or mucus-like or blood-tinged discharge, which could be the mucus plug. Losing the mucus plug is a sign labor is very near. Just how near though, we can’t say!
  • Braxton Hicks contractions. You’re probably still experiencing tightening in your abdomen, and it might be getting more intense. In fact, some pregnant women show up at the hospital thinking they’re in labor only to get turned away. Note that at 36 weeks pregnant, cramps that are at least as painful as menstrual cramps aren’t due to Braxton Hicks. If you’re experiencing something more severe, tell your OB right away.

Because at 36 weeks pregnant signs of labor can tough to tell apart from regular pregnancy discomforts, you’ll want to tell your doctor if anything seems out of the ordinary. It’s worth the call. And yes, even a trip to the hospital to find out it’s false labor is totally okay. The worst that could happen is you get sent home to relax and wait.


At 36 weeks, your pregnant belly probably won’t seem to change much from week to week. You’ve probably gained close to 25 to 35 pounds total—the recommended total amount of pregnancy weight gain for women of normal BMI. That’s probably making it challenging to move (or really… waddle) around. You won’t be putting on too much weight from here on out—probably only about a half-pound each week until baby’s born.

If you’re 36 weeks pregnant with twins, you’ve probably gained 35 to 45 pounds total. To say your belly is crowded is an understatement. While many twin moms deliver around week 36, there’s a chance you and your pair might hold on for a few more weeks. Remember that the longer you go, the less likely it is that your babies will need NICU time after birth. So even if you’re feeling super uncomfortable, hang in there and remember this extra time in utero is so good for the twins!

40 weeks pregnant

If you’re reading this, the chances are you’re still waiting for labour to begin. It will not be long now.

Happy due date! Since 40 weeks pregnant is baby’s official deadline, you’ve already made up the bassinet, installed baby’s car seat, packed your hospital bag, and set it by the door. Now, take care of some easy last-minute things, like making sure your cell phone is fully charged before you go to bed and filling the car with gas. At week 40 of pregnancy, some moms-to-be put a waterproof mattress cover on their bed, in case their water breaks in the middle of the night. It’s not a must, but it’s not a bad idea either, especially because once baby comes, there might be other messes to catch (breast milk, spit up, pee…). Week 40 of pregnancy can be mentally rough, since you’ll be constantly wondering when baby will decide to make his or her entrance and question every twinge you have. Try not to stress, and rest assured that baby will arrive when he or she’s ready—and your body will give you the right signals that it’s time.

How Big Is Baby at 40 Weeks Pregnant?

At 40 weeks pregnant, baby is the size of a watermelon. The average full-term 40- week baby measures about 20.2 inches from crown to heel and weighs 7.6 pounds.

40 Weeks Pregnant Is How Many Months?

40 weeks pregnant is nine months. Say it again because it feels good: Nine. Months. Pregnant. You made it!


During these last weeks of pregnancy, the same symptoms you’ve been having will likely continue. Your main job is to hang in there as you keep experiencing these:

  • Leg cramps. Stick with the calf and hamstring stretches to keep leg cramps from messing with your sleep. Pelvic pressure. Baby may drop even lower in your pelvis, making your pelvic discomfort worse.
  • Trouble sleeping. If you can’t sleep, it’s okay to get up and do something else, but keep to a calming activity such as reading or writing in a journal. Don’t start cleaning out your freezer or doing a Zumba video. Rest.
  • Fatigue. The fact that you can’t sleep isn’t really helping here. But since you may not have any plans, you may be able to sneak in an extra nap here or there—or at least take some quiet time to relax.
  • Contractions. Those Braxton Hicks contractions may eventually turn into the real deal, so if it seems like you’re having a lot of them, start timing them to see how far apart they are. If they get closer together, you’re in an early stage of labor.
  • Anxiety! Baby will get here when he or she gets here. Do your best not to stress.


You might be 40 weeks pregnant with no signs of labor. But at 40 weeks pregnant, signs of labor will be here very soon. Call your doctor right away if you have contractions that are more than a little uncomfortable or keep coming at regular intervals. The other 40 weeks pregnant sign of labor to look out for? A leak or flow of amniotic fluid—this means your water has ruptured or broken. You’ll likely know because it will be truly watery, not like typical discharge, and it doesn’t stop. At first you might think it’s pee, but then you will realize—nope! You’re in labor! Call your OB.


At 40 weeks pregnant, you may be getting antsy—after all, this is supposed to be your last week of pregnancy! You may be curious how to induce labor using natural methods. We recommend taking long walks and having sex. (Both are fun pastimes and could cause your body to start the process.) If you want to try acupuncture, that’s considered safe too. However, don’t take herbal supplements or drink castor oil—doctors say those methods are unsafe and probably won’t work anyhow. You might have heard that stimulating your nipples can induce labor—it can, but doctors recommend you don’t even try it. In fact, nipple stimulation can cause contractions that are too strong and may put baby’s well-being in jeopardy. Not worth it.

Now that you’ve reached your due date, your doctor might talk to you about inducing labor medically. Whether or not this is necessary will have to do with how baby’s doing in there. (The doctor might schedule this now if you have complications or are 40 weeks pregnant with twins.) If baby’s perfectly healthy and you have no complications, you might not need an induction at all and can keep sticking it out, even if it takes a couple more weeks. (Yes, weeks. Though chances are high that you’ll go into labor naturally by the end of next week.) It might be worth it to know that you waited it out until your baby was truly ready.
