You are now in the third trimester, and last, of your pregnancy! Your baby's crown-to-rump length is about 9.6 inches and your baby's total length is approximately 15.3 inches! Your baby now weighs about 2 pounds 3 ounces and is going to grow rapidly during this last trimester! Your uterus is about 2.8 inches above your bellybutton. If your baby were born now, it would have an 85% chance of surviving. Even though your baby is still not fully developed, she would be well within the limits of premature viability. You still have approximately 13 weeks left of your pregnancy, and during this time your baby must continue to grow and develop. If your baby was born at this time, she would have several complications that would require special attention. Because babies do not have adequate amounts of fat at this time, your baby would have to be kept inside of an incubator for warmth.
