In Canada, you're supported by a healthcare system that understands the nuances of this critical phase. Let's embark on a detailed exploration of what these last weeks hold for you and your baby.

Embracing the Third Trimester

In this third trimester pregnancy guide you will learn that as you step into the last trimester, it's a time of rapid growth and preparation. Both you and your baby are getting ready for the big day. The anticipation of meeting your little one is mixed with a range of emotions and physical changes. It's a period of watching, waiting, and, most importantly, nurturing.

Baby’s Development: A Miracle in Progress


  • 28 Weeks: Imagine a small, cozy bowling pin – that's the size of your baby now.

  • 30+ Weeks: Your baby is now gaining weight, almost like they're preparing for a big debut.

  • 36 Weeks: It's a time of repositioning as your baby gets ready for birth.

  • 39 Weeks: Full term now! Your baby is as ready as they'll ever be.

Navigating Pregnancy Symptoms


  • Braxton Hicks Contractions: These are like dress rehearsals for your body, a preparation for the main event.

  • Breast Changes: Your body is gearing up for nurturing your baby post-birth.

  • Discharge and Spotting: A common occurrence, but it's always good to stay vigilant.

  • Back, Hip, and Pelvic Pain: As your body accommodates the growing life within, it's normal to feel these aches.

  • Shortness of Breath: Your baby is claiming their space, but soon, you'll find relief as they move lower.

The Challenge of Sleep

  • Fatigue: It's like your body is telling you to slow down and rest up for the labor ahead.

  • Insomnia: With your mind racing about the future, finding peace can be challenging.

The Joy of Movement: Kick Counts

Feeling your baby move is one of the most exciting parts of this trimester. It's not just a sign of life, but a connection between you and your little one.

Weight Gain: A Healthy Progression

Gaining weight is a positive sign of your baby's growth. Embrace it as a healthy part of this journey.

Your Prenatal Health Care in Manitoba

What's happening during 3rd trimester?


With each pregnancy, you should be immunized with Tdap (tetanus, diphtheria, pertussis) vaccine between 27 and 32 weeks (new recommendation effective October 2018). This protects your newborn baby for the first few months of life.


You may need follow up care if your tests results show you have Rh negative blood and do not have antibodies for Rh factor. Your provider may give you an injection of RhoGAM at 28 weeks of pregnancy. This prevents a serious blood condition from developing in your baby.


You will also receive a vaginal/anal swab to test for Group B Streptococcus (GBS) around 35 to 37 weeks.


  • GBS is bacteria that are commonly found in the vagina and anus. It is not harmful to you but can be transferred to your baby during delivery and cause a serious infection. If you test positive for GBS, you will receive an intravenous antibiotic during labour.

You will be tested again for sexually transmitted infections.

From 37 weeks until you deliver, you will see your health care provider weekly.

Conclusion

The third trimester is a time of profound transformation and growth. In Manitoba, you're surrounded by a supportive healthcare system and a community that understands and respects the journey of childbirth. Embrace this time with patience and excitement, and prepare to welcome your little one into the world.
