In your first month of pregnancy the embryo resembles a tadpole. The arms and legs begin as tiny buds. Nerve development begins and the backbone, spinal cord and lungs begin to form. The heart also begins to develop and will start beating near the end of this month. The placenta is present but not fully developed. The embryo will be approximately ½ inch long and will weigh a fraction of an ounce at the end of the first month.

During the second month, the embryo goes through rapid development. The heart is functioning. All major organs and body systems begin to develop, including the brain, lungs, liver and stomach. Eyelids form but remain sealed shut. The inner ear begins formation, as do the face and features. The first bone cells appear. Ankles, wrists, fingers, toes and sexual organs are developing. The placenta is functioning and the umbilical cord is present. The baby looks more like a person than a tadpole and will measure slightly more than an inch and weigh less than 1ounce at the end of this month.

During the third month, Ultrasona welcomes patients to witness the miraculous development of their baby. The heart has four chambers and beats at 120 to 160 beats per minute. Eyes are almost fully developed but still remain shut. The fingers and toes are more defined and now have soft nails. Earlobes are formed. Buds which will become teeth have formed under the gums. Kidneys are developed and begin draining urine to the bladder. Most bones have begun to develop, and the umbilical cord becomes fully formed. By the end of this month, the baby will be about 4 inches long and weigh slightly over an ounce.
