The third trimester marks the home stretch, as she gets ready for the birth of the baby. The fetus continues to grow in weight and size, and the body systems finish maturing. She may feel more uncomfortable now. She will continue to gain weight and begin to have false labor contractions (Braxton-Hicks contractions) along with other pregnancy symptoms (heart burn, swollen ankles etc.)
Hope this helps!
