Prenatal Visits in Third Trimester

Pregnancy

Obie Editorial Team

Congratulations on reaching your third trimester, a pivotal stage of your pregnancy journey, spanning from week 28 through week 40. You're in the home stretch! During this time, expect more regular check-ins with your healthcare provider, tailored to your unique pregnancy progression. These could range from monthly to weekly appointments as you approach the finish line.

In response to the COVID-19 pandemic, the modern approach to prenatal care has evolved. Emphasizing safety, this method integrates virtual visits with traditional in-person consultations, ensuring comprehensive prenatal care while minimizing unnecessary exposure. 

Doctor’s Appointments

Your third-trimester appointments, much like those in the second trimester, typically begin with a comprehensive physical exam. This includes a pelvic exam and possibly an ultrasound. Key assessments such as your blood pressure, weight, and fetal movements will be monitored closely, along with your baby's heartbeat. It’s also a time to observe any swelling. You might be encouraged to keep track of your baby’s movements as a way to gauge their well-being.

Your health is paramount, and open communication with your doctor is crucial. Expect to discuss any symptoms or contractions you might be experiencing. This dialogue provides valuable insights into your and your baby’s health and readiness for delivery.

As you near the culmination of your third trimester, appointments often focus on assessing your baby’s position. If the baby is in a breech position (feet or rump first), your doctor may suggest gentle techniques to encourage your baby to turn.

Your healthcare provider will also examine cervical dilation and effacement (thinning), key indicators of impending labor. This assessment can help predict the timing of your baby's arrival.

Tests and Screenings

Throughout this crucial trimester, specific tests provide an enhanced understanding of both your health and your baby’s condition. These evaluations are routine but essential.

  • Group B Strep: During the third trimester, you'll be screened for group B streptococcus, or Group B strep (GBS). The American College of Obstetricians and Gynecologists recommends universal GBS screening between 36 0/7 and 37 6/7 weeks of gestation. This screening is crucial to prevent potential infections in newborns.
  • Blood and Lab Tests: If you have a history of anemia, additional blood tests check your iron levels. Similarly, if there's a risk of sexually transmitted infections like gonorrhea, HIV, or Chlamydia, further testing ensures proactive care. Additionally, blood glucose levels and urine protein are evaluated to manage risks such as preeclampsia.
  • Ultrasound: For those with a previously identified low-lying placenta or placenta previa, follow-up ultrasounds determine the placenta's current position, ensuring readiness for delivery.
  • Non-Stress Test: Especially in the final weeks of pregnancy, the non-stress test is vital for assessing your baby’s heartbeat, particularly if you pass your due date.

Your third-trimester consultations and tests aim to prepare you for labor and delivery. Make these visits your opportunity to address any questions or concerns, ensuring you’re informed and ready for the exciting journey into parenthood. Stay proactive, engaged, and confident as you navigate these final steps toward meeting your baby.
