Week 27 of Your Pregnancy

A look at your body, your baby, and more

week 27 pregnancy highlights


Welcome to week 27 of your pregnancy, the final week of your second trimester. Your baby is likely moving quite a bit these days, and it’s important that you do too (opting for safe activities if exercise is advised, of course). While you may have enjoyed less fatigue this trimester, that may change in the weeks ahead.

Your Trimester: Second trimester

Weeks to Go: 13

Verywell Checklist

  • Continue taking prenatal vitamins.
  • Continue drinking about eight to 12 glasses of water a day.
  • Continue doing your Kegel exercises daily.
  • Buy a sitz bath and witch hazel if you have hemorrhoids.
  • Add fiber- and magnesium-rich foods to your grocery list.
  • Start car seat research.

Symptoms This Week

Weight Gain

You’re continuing to gain the weight you need to properly support your growing baby—and that weight settles in many different areas. For instance, the average pre-pregnancy breast weighs about seven ounces. But by the end of pregnancy, each breast can double that amount.

Baby's Kicks

As your baby’s kick count continues to increase, so may the bond—and worry—you feel. Once your baby reaches this level of activity, you may become concerned about how often you should feel your baby-to-be move.

At the same time, it may be hard to distinguish between your own gas and baby’s hiccups, tumbles, and kicks. Don’t worry: You’ll gradually come to learn what’s what. In fact, soon enough you’ll likely be able to predict baby’s sleeping and waking cycles.

If your pregnancy is considered high risk, your healthcare provider may advise you to set aside time daily to count fetal movements beginning around now. Regardless, if your baby seems less active than usual, discuss it with your healthcare provider.

New Symptoms

Hemorrhoids are very common at this stage of pregnancy, and the reasons are twofold. First, your amped-up blood flow and growing uterus cause a lot of pressure inside your abdomen, prompting veins in your rectum to swell.

Second, the progesterone uptick you’re experiencing causes food to move through your intestines more slowly, which can result in constipation.

Your Baby's Development

Your baby is steadily growing, measuring 13¾ inches long and weighing 2¼ pounds by the close of week 27. If you’re carrying multiples, up until this point, your babies have been growing at roughly the same rate as singletons. However, triplet and quadruplet pregnancies begin slowing around this time, whereas the same thing occurs in twin pregnancies around week 30.

Baby’s brain is more active than ever. His or her newly-formed neurons and connections are the reason your baby-to-be may be able to discern your voice from others by now.

Finally, as your baby’s lungs approach maturity and he or she continues to practice swallowing amniotic fluid, hiccups are bound to occur. You might even feel them as muffled, rhythmic movements in your uterus.

Self-Care Tips

Hemorrhoids are a common problem at week 27 and beyond. Here are some ways to help ease your discomfort:

  • Take a sitz bath, where you gently run warm water over you hemorrhoids while situated on a mini-tub that fits directly over your toilet.
  • Avoid standing for long stretches.
  • Consume plenty of fiber, such as whole wheat, flax, fruit with skins, vegetables, brown rice, and lentils.
  • Drink plenty of water to keep your digestive tract moving.
  • Exercise regularly to help move waste through your intestines.
  • Don’t strain while on the toilet. Constipation-related straining can actually cause hemorrhoids.

A Tip From Verywell

If you're dealing with hemorrhoids, try adjusting your diet to ease discomfort. Eat foods high in fiber and magnesium and drink plenty of water.

Special Considerations

If you’ve been diagnosed with placenta previa, where the placenta is covering all or part of your cervix, and it has yet to resolve on its own, it may be time that your healthcare provider asks you to alter your daily activities.

For instance, your doctor or midwife may advise that you avoid exercise and sexual intercourse. In some cases, bed rest may also be advised.

At Your Doctor’s Office

The CDC recommends that all pregnant women get the whooping cough vaccine (Tdap) between 27 and 36 weeks of each pregnancy. Because babies cannot be vaccinated against whooping cough (also called pertussis) until they are two months old, it’s important that you pass the antibodies to your baby before birth by getting the Tdap yourself.

To maximize your antibody response, it’s best to get the shot as close to 27 weeks as possible. And there’s no need to worry: The vaccine is safe for you and your baby. The most common side effects include:

  • Pain, redness, or swelling at injection site
  • Headache
  • Body aches
  • Tiredness

It’s important that your partner and any others who will be close to your baby be vaccinated as well.

Upcoming Doctor's Visits

Earlier in your pregnancy, your blood type and Rh factor (a type of protein in red blood cells) were determined. If you learned that you are Rh-negative, your healthcare provider will take the necessary steps to help keep you and your baby safe at your next prenatal visit.

Advice for Partners

A majority of hospitals require that all new parents have an infant car seat before taking their newborn home. Before helping to choose one, know that:

  • All babies need to ride in a rear-facing, infant-only or convertible car seat until the age of 2, or until the child has reached the highest height or weight allowed by the seat’s manufacturer.
  • Consumer Reports advises that it’s best to avoid buying a used car seat, since it can be difficult to determine crash history, expiration dates, and recalls.
  • You can get help with installation. Consider reaching out to a child passenger safety technician (CPST) who can ensure your seat is properly installed. Your local police or health department may also offer this service.

The U.S. Department of Transportation’s Ease-of-Use Guide may help you determine what seat is best for your family.
