3rd Trimester

During the third trimester, your prenatal visits will increase. The third trimester screening prenatal visit would be quite similar to the previous visits. Your blood pressure and weight will be checked and a urine test may be conducted. You will be asked to be aware of baby movements and immediately alert if the baby seems to be less active than before.

Additionally, during the third trimester of pregnancy, you would be screened for group B streptococcus (GBS). You may also be asked to take some third trimester tests for sexually transmitted infections (STIs). You may also have to take a non-stress test (NST) that measures your baby’s heart rate as they move around.

Towards the end of the third trimester, your doctor will estimate the baby’s weight and position in the uterus. You may also be asked to have an ultrasound scan in the third trimester to assess the baby’s position and level of amniotic fluid around the baby. As your due date approaches, your doctor may also perform a pelvic exam to detect cervical changes for dilation and efface.
