The first trimester is a time of remarkable growth and development. The single-celled, fertilized egg divides rapidly into an embryo, then a fetus. Although there is much growth and maturation to come, by the end of this trimester the fetus has a recognizably human form, with facial features, sense organs, fingers and toes on the end of tiny limbs, and even tooth buds, fingerprints, and toenails. The brain, nervous system, and muscles are all functioning and the fetus can perform involuntary reflexes, such as moving about vigorously, swallowing, hiccupping, yawning, and urinating.

Second Trimester

The second trimester of pregnancy is a time of continuing growth and development. All the body systems are in place, but the fetus is not yet capable of independent life. The maternal discomforts of the first trimester, such as morning sickness and tiredness, start to settle at the beginning of the second trimester. Steadily increasing blood volume and a more dynamic circulation give the mother-to-be a healthy glow. The top, or fundus, of the uterus, should rise above the pelvis in the fourth month, making the pregnancy obvious. Over the course of the second trimester, the fetus will more than triple in size, and its weight will increase by around 30 times.
