Key Takeaways

At 36 weeks pregnant, your baby is smoothing out and filling in — Mayo Clinic says the skin becomes smooth as fat is added, the limbs look chubby, and most babies have turned head down by now. Mayo gives no measurement this week (about 2,100g at week 34).

If your baby is still breech, there is a calm plan. SOGC explains that at about 36 weeks your provider may attempt an external version, rotating the baby from the outside — a maneuver that works about half the time.

This is Group B Strep swab week for many. SOGC notes you will usually be screened for GBS between 35 and 37 weeks, and that if you test positive you will be treated with intravenous antibiotics when you go into labour.

Your Baby at 36 Weeks: Development & Growth

At 36 weeks pregnant, your baby is adding fat and smoothing out, and has most likely turned head down. Mayo Clinic notes the skin is becoming smooth as fat is laid down beneath it and the limbs are starting to look chubby. Mayo Clinic does not give a length or weight at week 36, so the closest figures come from its neighbouring weeks.

The change this week is fat, and it shows. Mayo Clinic says that at week 36 "your baby's skin is becoming smooth as more fat is added under the skin" and "the limbs start to look chubby." That padding is what will keep your baby warm after birth.

Position is the other headline. Mayo Clinic notes that "most babies have turned head down by this point" — the curled, head-low posture that sets up for birth. Your baby is getting settled.

Mayo Clinic does not publish a measurement at week 36. For a sense of scale, it puts week 34 at "nearly 12 inches (300 millimeters) long from crown to rump" and "more than 4 1/2 pounds (2,100 grams)," and week 38 at "about 6 1/2 pounds (2,900 grams)." Your baby this week sits somewhere in between.

Space is tighter now, and that is expected. Mayo Clinic notes that by week 35 your baby "fills most of the space in the amniotic sac and has less room to move," but adds that "you'll probably still feel lots of stretches, rolls and wiggles." Less room, not less movement.

Your Body at 36 Weeks: Symptoms & Changes

At 36 weeks pregnant, the third trimester is heavy and close. SOGC lists tender breasts, constipation, backaches, headaches, mood swings and leg cramps among the common discomforts of pregnancy. This is also the stretch when the GBS swab is taken and, if your baby is breech, when a turning procedure may be discussed. Every pregnancy is different.

Baby's position may be on your mind, and there is a plan for it. If your baby is breech near term, SOGC explains that at about 36 weeks "your health care provider may attempt an 'external version' where he or she will attempt to rotate the baby from outside." SOGC adds that this "works about half the time," and to "have the greatest chance of success, this maneuver should be attempted between 35 and 36 weeks gestation."

A breech baby does not mean something has gone wrong. SOGC notes that "there is usually no obvious reason why a baby does this," and that if turning is not attempted or is not successful, "breech babies can be delivered either vaginally or by a Caesarean section" — a decision to talk through with your provider, weighing "the risks and benefits of each mode of delivery."

Not every tightening is labour. Braxton Hicks turn up often by now — Mayo Clinic describes them as tightness that "vary in strength and length" and "often come and go," more likely in the afternoon or evening or after activity. Sit down, change position, have a drink, and they usually fade. The difference is whether they build: SOGC's test is contractions that keep coming and "don't go away when you change your activity." You still have a week to go before term, so that pattern means a call.

The symptoms of late pregnancy may still be with you. SOGC lists tender or swollen breasts, constipation, gas and bloating, backaches, headaches, mood swings and leg cramps among the common discomforts, and reminds mothers that "every pregnant woman is different." A heavier, lower bump is part of this final stretch.

Headaches deserve their own line. Most are the ordinary kind — poor sleep, a tight neck, a long day on your feet. But SOGC names "headaches, blurred vision, dizziness, nausea or vomiting, or shortness of breath" among the symptoms to watch for with preeclampsia, a complication it describes as "marked by high blood pressure and the presence of protein in the urine." A headache that is severe, will not shift, or comes with vision changes or sudden swelling is worth a call — not a dark room and a wait.

Mood is worth watching honestly. SOGC notes that while mood swings "are not usually severe," it is also true that "depression or disruptive mood swings are not normal and it is important to seek help for these more serious concerns." Reaching out is the right move, not an overreaction.

What to Do at 36 Weeks Pregnant

NUTRITION AT 36 WEEKS PREGNANT

Keep the third-trimester calories, and keep them useful. SOGC states: "In the third trimester, you need about 450 extra calories," noting this "generally equates to 2 or 3 additionally servings from any of Canada’s Food Guide’s food groups" — for example, a piece of toast and a cup of milk, or an apple and some yogurt. Take it in small helpings across the day rather than two or three big meals: there is less room under your ribs now, digestion is slower, and hunger comes back faster than it used to.
Hold your iron steady. SOGC advises increasing "your daily iron intake to 27mg daily during the final six+ months of pregnancy to support an increase in red blood cells and fetal tissues," and notes that "like most women, you may need a good supplement to meet this need." Demand stays high right through to birth.
Check your choline. SOGC notes that "choline intake above 450mg a day is linked to improved fetal stress responses and a reduced risk of neural tube defects," adding that "this vitamin may not be found in your prenatal daily vitamin." Worth a glance at the label.

WHAT SUPPLEMENTS TO TAKE AT 36 WEEKS PREGNANT

Keep taking 400mcg of folic acid daily. The Public Health Agency of Canada states that "a daily multivitamin with 400 mcg (0.4 mg) of folic acid is recommended for anyone who could become pregnant," and advises: "Continue taking folic acid throughout your pregnancy and while breastfeeding."
Don’t raise your folic acid dose on your own. The Public Health Agency of Canada advises: "You should not increase your dose of folic acid beyond 1 mg per day without talking to your health care provider." A higher dose is a conversation, not a decision for the supplement aisle.
Consider vitamin D with the finish line in mind. SOGC notes that "taking a vitamin D supplement of 2000IU in the last six months of pregnancy will enhance the vitamin D content of your breast milk towards meeting the daily needs of your breastfeeding infant." Check what your prenatal already covers.

LIFESTYLE TIPS AT 36 WEEKS PREGNANT

Pack the hospital bag now. SOGC offers a checklist "to take with you to the hospital or birthing centre" that includes, for your stay, "1-2 nightgowns," a "robe and slippers," "your cell phone and charger" and "a package of large pads for postpartum flow." For the baby, SOGC lists a "car seat," "clothing – undershirts, sleepers, hats," "receiving blankets" and "diapers and wipes." The car seat is the one you cannot leave without. Call ahead too — hospitals differ on what they supply and what they want you to bring.
Get to know your baby’s movement pattern. SOGC notes that movements "tend to be consistent for any one baby, in any one pregnancy," and suggests that if you count, "try to do it at the same time each day" — often in the evening, lying down, when babies tend to be more active. Count everything, not only kicks: SOGC counts "kicks, flutters, or rolling movements," so rolls, turns and stretches all register.
Ask about the GBS swab if it hasn’t happened yet. SOGC notes you "will usually be screened for GBS between 35 and 37 weeks of gestation," a "test that is easy and painless," done by "swabbing the vagina and rectum with a cotton-tipped swab" — and that "you have the option of doing the swabbing yourself."
Keep caffeine to 300mg a day. Health Canada recommends a maximum daily caffeine intake of 300 mg for people who are pregnant. For reference, Health Canada puts one 8oz (237ml) cup of brewed coffee at 135mg — so roughly two cups is the ceiling, and that total includes tea, cola and chocolate.

When to Contact Your Doctor or Midwife

Week 36 is mostly steady preparation, not alarm. But some symptoms should always be checked. Contact your doctor, midwife or other health care provider if you experience:

A change in your baby's movements, or fewer movements than usual. SOGC advises being "aware if any changes in your baby's usual activity level, especially in the third trimester," and to do a kick count "count the baby's movements for 2 hours." SOGC is specific: "If you don't feel 6 movements (such as kicks, flutters, or rolling movements) in 2 hours, you should contact your health care provider as soon as possible." SOGC adds that "if you ever have concerns regarding your baby's movement pattern, you should have the baby assessed as soon as possible," and that mothers "should always trust their intuition." Less room to move does not mean fewer movements.
Signs of preeclampsia. SOGC describes preeclampsia as "marked by high blood pressure and the presence of protein in the urine," and names "headaches, blurred vision, dizziness, nausea or vomiting, or shortness of breath" among the symptoms to watch for. Sudden swelling of the face, hands or feet belongs on that list. Do not wait for your next appointment — call the same day.
Signs of preterm labour — this matters right up to 37 weeks. SOGC advises: "Contact your health care provider right away if you are having any of the following: Backache that comes and goes; Regular contractions less than 10 minutes apart; Cramping in your lower abdomen; Fluid leaking from your vagina; Pressure in your pelvis or vagina; Vaginal bleeding." SOGC stresses that "it is very important to go to the hospital if you have regular contractions at any time before 37 weeks that don't go away when you change your activity," and warns that "staying home thinking that this couldn't possibly be labour because it is too early is dangerous."
Your water breaking, or fluid leaking. SOGC lists "fluid leaking from your vagina" among the signs to report right away. Note the time it happens and contact your provider, because the GBS plan and next steps depend on it — SOGC notes that if you test positive you are "treated with intravenous antibiotics when you go into labour, or if your water breaks early."
Any vaginal bleeding. SOGC lists "vaginal bleeding" among the signs to contact your provider about right away. Reach out promptly, and if bleeding is heavy or you feel very unwell, seek emergency medical care immediately.
Signs of a possible infection. SOGC notes that you "may have an infection in your vagina or cervix if you notice an unusual vaginal discharge, have pain in your pelvis or groin area, or a fever," and advises to notify your health care provider. A bladder or kidney infection can show up as pain when you urinate or needing to go often.
Persistent low mood or disruptive mood swings. SOGC advises that "depression or disruptive mood swings are not normal and it is important to seek help for these more serious concerns."

Questions fréquemment posées

What position is my baby in at 36 weeks?

By 36 weeks, most babies have settled head down. According to Mayo Clinic, "most babies have turned head down by this point," and the skin "is becoming smooth as more fat is added under the skin." If your baby is not head down, Mayo Clinic notes your "healthcare professional may talk with you about ways to move the baby in that direction," usually "done around week 37."

What happens if my baby is breech at 36 weeks?

There is a calm, established plan. The Society of Obstetricians and Gynaecologists of Canada (SOGC) explains that if your baby is breech at about 36 weeks, "your health care provider may attempt an ’external version’ where he or she will attempt to rotate the baby from outside." SOGC says this "works about half the time," and if it succeeds "it is possible to have labour and delivery just as if the baby had been head down all along." SOGC also notes that "there is usually no obvious reason why a baby does this," and that a breech baby "can be delivered either vaginally or by a Caesarean section," a choice to discuss with your provider.

How do I tell Braxton Hicks from real labour at 36 weeks?

By what they do next. Mayo Clinic describes Braxton Hicks as tightness that "vary in strength and length" and "often come and go" — irregular, and usually easing when you sit down, change position or have a drink. Labour contractions do the opposite: they keep coming, get stronger, and, in SOGC’s words, "don’t go away when you change your activity." Because you are still before 37 weeks, SOGC is firm that regular contractions that don’t settle mean going to the hospital, and warns that "staying home thinking that this couldn’t possibly be labour because it is too early is dangerous."

How big is my baby at 36 weeks pregnant?

Mayo Clinic does not publish a length or weight at week 36 — it describes the changes as smoother skin and "chubby" limbs. For scale, Mayo Clinic puts week 34 at "nearly 12 inches (300 millimeters) long from crown to rump" and "more than 4 1/2 pounds (2,100 grams)," and week 38 at "about 6 1/2 pounds (2,900 grams)," so your baby this week falls between those points.

What is the Group B Strep test at 36 weeks?

It is a routine swab. The Society of Obstetricians and Gynaecologists of Canada (SOGC) notes you "will usually be screened for GBS between 35 and 37 weeks of gestation," by "swabbing the vagina and rectum with a cotton-tipped swab," and that "you have the option of doing the swabbing yourself." SOGC explains that "around 15-40% of all pregnant women are GBS positive," and that if you test positive "you will be treated with intravenous antibiotics when you go into labour, or if your water breaks early." SOGC adds that even with a planned Caesarean "you will still need to be screened for GBS in case your water breaks or you go into labour before the scheduled delivery."

What should I pack in my hospital bag?

The Society of Obstetricians and Gynaecologists of Canada (SOGC) offers a checklist "to take with you to the hospital or birthing centre." For your stay, SOGC lists "1-2 nightgowns," a "robe and slippers," "your cell phone and charger" and "a package of large pads for postpartum flow." For the baby, SOGC lists a "car seat," "clothing – undershirts, sleepers, hats," "receiving blankets" and "diapers and wipes." The installed car seat is the item you will not be discharged without. Check with your own hospital as well — supplies and rules vary from one unit to the next.
