Staying Safe & Prepared as Delivery Nears
You’re in the home stretch! The third trimester (weeks 28–40+) is all about monitoring your health and your baby’s well-being as labor draws near. These screenings are designed to catch any last-minute complications and help plan a safe, smooth delivery.
Here’s what to expect:
1. Group B Strep (GBS) Test
When: Usually between 36–37 weeks
This test checks for Group B Streptococcus, a common type of bacteria that can be passed to the baby during birth.
How it’s done:
A quick swab of the vagina and rectum is sent to the lab. If positive, IV antibiotics during labor will help prevent infection in the baby.
Don’t worry — GBS isn’t harmful to you, but treating it in labor protects your newborn.
2. Blood Pressure Monitoring
Your provider will check your blood pressure at every visit in the third trimester.
Why it matters:
High blood pressure can be a sign of preeclampsia, a potentially dangerous condition that requires close monitoring or early delivery.
Be sure to tell your provider if you experience:
- Swelling in the face or hands
- Headaches
- Blurry vision
- Sudden weight gain
3. Non-Stress Test (NST) and Biophysical Profile (BPP)
These are special tests that assess your baby’s health in the final weeks — especially if:
- You have a high-risk pregnancy
- You’re past your due date
- Baby’s movements feel reduced
- You have conditions like diabetes or hypertension
Non-Stress Test (NST):
Monitors baby’s heart rate in response to movement using external monitors. It’s painless and takes about 20–40 minutes.
Biophysical Profile (BPP):
Combines an ultrasound and NST to check five things:
- Baby’s movements
- Muscle tone
- Breathing motions
- Amniotic fluid level
- Heart rate
4. Cervical Checks Near Due Date
When: Typically begin around week 36–38, depending on your provider.
Your provider may check your cervix for dilation, effacement, and position to assess whether your body is preparing for labor.
This is optional and not always necessary, especially if you’re not experiencing contractions.
5. Fetal Position and Birth Planning
As delivery approaches, your provider will check baby’s position:
- Head down (vertex) is ideal for vaginal birth
- Breech (bottom down) or transverse (sideways) may require further evaluation or a C-section plan
If your baby isn’t head-down, your provider may suggest options like an external cephalic version (ECV) — a gentle attempt to turn baby manually.
You’ll also discuss:
- Birth preferences and pain management options
- Signs of labor
- When to head to the hospital or birthing center
- Who to call when labor begins
Final Thoughts
The third trimester is filled with anticipation, questions, and important decisions. These tests and screenings help ensure that both you and your baby are in the best possible condition for delivery.
Stay in close communication with your provider, track your baby’s movements, and trust your instincts — you’re almost there!
