35-Week Appointment: What to Expect

The 35-week prenatal appointment marks a significant transition in the third trimester of pregnancy. This visit moves beyond routine monitoring to include crucial preparations for labor and delivery. At this stage, you are nearing the end of the bi-weekly appointment schedule before visits increase in frequency. The check-up combines standard physical examinations with a specific, time-sensitive medical screening.

Standard Physical Examination Components

During the 35-week appointment, the physical examination monitors maternal health metrics. Your blood pressure is checked to screen for signs of preeclampsia, which can develop late in pregnancy. Weight gain is also tracked to ensure it remains within a healthy range.

The provider listens to the fetal heart rate using a Doppler device to confirm the baby’s steady rhythm. A measurement of the fundal height is also performed, measuring the distance from the pubic bone to the top of the uterus. This measurement correlates roughly with the number of weeks of gestation, offering a quick assessment of the baby’s growth rate.

If the fundal height measurement is significantly larger or smaller than expected, it may prompt further investigation. An ultrasound might be ordered to assess the baby’s size and the amount of amniotic fluid.

The Group B Strep Screening

The Group B Streptococcus (GBS) screening is typically performed between 35 and 37 weeks. GBS is a common bacterium that lives in the gastrointestinal and genitourinary tracts of many healthy adults. Approximately 15 to 40% of pregnant women are colonized with GBS without experiencing symptoms.

GBS can be passed to the baby during a vaginal birth, potentially leading to serious complications like sepsis, pneumonia, or meningitis in the newborn. The screening involves a simple swab of the lower vagina and the rectum, which is sent to a laboratory to be cultured for the presence of the bacteria.

If the test result is positive, it means the bacteria is present. A positive result leads to a recommendation for intravenous (IV) antibiotics, usually penicillin, administered during labor. Antibiotics given for at least four hours before delivery significantly reduces the risk of the baby developing an early-onset GBS infection.

Preparing for Labor and Delivery Logistics

The 35-week appointment is a time for detailed discussion and planning for the final weeks of pregnancy and the birthing process. A physical check of the baby’s presentation is typically performed, either through palpation of the abdomen or sometimes with an ultrasound. The provider assesses the fetal position, ideally confirming the baby is in the cephalic, or head-down, position for birth.

If the baby is found to be in a breech position (bottom or feet first), your provider will discuss potential next steps. While there is still time for the baby to turn spontaneously, options like an external cephalic version (ECV) to manually turn the baby may be discussed if the breech presentation persists near term. The conversation will also cover the distinction between Braxton Hicks contractions and true labor signs, providing instructions on when to call the medical team and when to head to the hospital.

This visit is also the time to finalize logistical details regarding the birth experience, often including a review of the birth plan. You will discuss pain management options, hospital expectations, and what to pack in your hospital bag. The provider will confirm the schedule change to weekly appointments going forward, ensuring close monitoring until delivery.
