You’ve made it to your third trimester. What an accomplishment — your body has grown an entire human being over these past several months! Now, you’re anticipating your little one’s delivery and in the homestretch before your due date.

In this article, the baby experts at Mustela provide a list of what to expect and how to prepare during your third trimester.

Third Trimester Basics

The third trimester lasts from week 28 to week 40, or months seven, eight, and nine. You will finally meet your little one during this time!

Most women gain around 11 pounds during their third trimester. Of course, every woman is different, so give or take a few pounds.

You’ll also experience some anticipation and anxiousness while waiting to meet your little one. And remember those yucky first trimester symptoms? Be prepared for some of those to symptoms to reappear during this trimester.

Third Trimester: What To Expect

Your Body

Your body is gearing up for delivery. Expect several changes during these last three months.

Lack Of Appetite

Your belly will fill up faster now due to the pressure of your growing baby pushing against your abdomen. Liquids fill your stomach quickly, leaving less room for food. So when eating a meal, just sip on liquids rather than drinking a whole glass.

We suggest eating several small meals and snacks throughout this trimester. This allows you to get the nutrition needed to support you and your little one without making you feel bloated.

Abdominal Achiness

In your second trimester, you experienced round ligament pain. You will continue to feel these growing pains, but they may now be accompanied by sharper aches as well. This is normal as your round ligaments continue to stretch.

High Blood Pressure

Changes in your blood pressure may occur during this trimester. Your doctor will keep an eye out for preeclampsia, which is a condition that’s marked by high blood pressure in pregnant women who don’t have a history of blood pressure.

Preeclampsia can be serious if not monitored closely, so it’s important to take your doctor’s advice in order to avoid it.

Back Aches

Think about it: you’re carrying more weight than you ever have before. This weight gain took place over only a few months, so back aches are expected.

Because of this pain, typical day-to-day activities may become more difficult during the third trimester. Don’t hesitate to ask for help from friends and family to lessen the strain on your back.

Braxton Hicks Contractions

Braxton Hicks contractions are contractions that occur before real labor. Some women report feeling these contractions even as early as the second trimester.

Your body is gearing up for delivery, so this is something you can expect during the last few months. If these contractions get stronger and more frequent, reach out to your doctor.

Other Changes

Other changes in your body during this time include:

  • Constipation
  • Heartburn
  • Occasional headaches
  • Increased vaginal discharge
  • Clumsiness
  • Mild swelling in your ankles or feet
  • Varicose veins
  • Hemorrhoids
  • Shortness of breath
  • Restless Leg Syndrome
  • Itchy abdomen
  • Enlarged and leaky breasts
  • Fatigue
  • Crazy dreams
  • Lack of bladder control
  • Pelvic pressure
  • Difficulty sleeping

Your Emotions

How are you doing? You may or may not be able to answer this question.

Your emotions may level out at this trimester, and you’ve reached the point of relaxation. (Yay, your baby’s coming soon!) Or the complete opposite can happen. Maybe you’ve reached the point of heightened anxiety. You’ve become frantic in your emotions and thoughts, trying to get every last-minute detail handled.

Both of these emotions are completely normal. Additional emotional changes during this time include:

  • Increased excitement
  • Increased apprehension
  • Continued absentmindedness
  • Dreaming about your baby
  • Increased eagerness
  • Relief that you’re almost there
  • Irritability and oversensitivity
  • Impatience and restlessness

Third Trimester: How To Prepare

Since you’ll be giving birth to your bundle of joy at the end of this trimester, it’s important to make sure everything is in place before delivery. The baby experts at Mustela have a few items on the agenda when it comes to being prepared during your last trimester.

Hospital Classes And Tours

Your local hospital has several classes for you to choose from, including birthing classes, breastfeeding classes, and CPR classes. If this is something you’re interested in, be sure to contact the hospital to find out the dates to schedule your class.

Additionally, consider touring the hospital before giving birth. They’ll show you everything from where to go to what they’ll do once you arrive. Your partner may want to join you on this tour as a way of bonding and being prepared.


Mustela supplies for hospital bag

You’re due any day now, and you’ll want to be prepared. Pack your overnight bag, along with the diaper bag containing all of your baby’s essentials.

You may also want to consider packing your Mustela Maternity Skincare Set to continue your skin care routine at the hospital and your Body Firming Gel to use after birth to help tone and firm your skin.

If you have any other children, they will likely need to spend a couple of days at a trusted babysitter’s house while you are in the hospital. Prepare an overnight bag that’s ready to go for them as well. After all, you wouldn’t want to go into labor and start scrambling to get everything packed!

Installing The Car Seat

You will need to have a car seat installed sometime during the third trimester. Check with your local law enforcement office and schedule a car seat inspection before delivery. We know that making sure your little one is safe while traveling is a top priority!

Planning For Waiting

Once you’re admitted to the hospital, it might become a waiting game. You really have no idea how long you’ll be waiting, so be prepared by bringing books or some form of entertainment to keep your mind off the pain.

Last-Minute Touch-Ups

Check out any last-minute items on your list that you wanted to accomplish before your baby arrives. Getting the nursery and closet ready and washing clothes are just a few last-minute ideas. Also, purchase any additional items for your little one that you didn’t receive from your baby shower.

Enjoy Your Third Trimester
