Zygote
After conception, when sperm fertilizes the egg, the baby's formation starts as a singular cell called a zygote. The zygote is microscopic and contains the entire DNA blueprint information regarding the cellular makeup of the child. This is the first stage of fetal development, MedlinePlus reports.
Cellular Division
The next stage in fetal development has the name of the blastocyst. The tiny zygote begins to divide again and again, forming new structures and a protective membrane to cover itself. At day six, the blastocyst enters the womb of the mother and implants itself, beginning another stage of development of the baby.

Embryo
After the blastocyst has implanted itself within the womb, new cellular divisions occur. The womb works to nourish the small baby, now called the embryo. The embryo continues to divide into its distinguishable external features. The first trimester stage is called development of the embryo, MedlinePlus reports.
The Gestational Period
The gestational period occurs between two to eight weeks after conception, during which time continued development of major organs occurs within the baby. The baby’s features become defined and recognizable. Eyelids form as well as the tiny spinal column. The hands and feet develop fingers and toes. Specific facial features form during this stage, as do the intestines, meaning the digestive system begins to take form.

The Embryonic Period
This stage occurs at the end of the week eight of the gestational period. The baby has the ability to make a fist and its eyes remain closed now until the opening after the 28th week of development, MedlinePlus reports. The bones of the baby become harder during this stage. The baby starts to move around within the womb and can hear during this stage. At this point, the embryonic stage begins the second trimester.

The Second trimester
During the 26th week, the beginning of the second stage of the trimester occurs, MedlinePlus indicates. The baby continues to develop and the mother notices a change in her appearance. The baby begins to become much larger and causes the mother’s abdomen to become distended. A doctor can, at this point, hear the baby’s heartbeat with a stethoscope. The mother also can feel the baby kick inside her womb. The baby becomes active during this stage of development, MedlinePlus states.

The Third Trimester
The baby has the ability to open its eyes in the 28th week of development, MedlinePlus reports. This begins the last trimester of the baby's development in the womb. The baby‘s developmental age is now well over six months. The baby continues to grow throughout the 42 weeks, developing the final distinguishable features from its individual DNA makeup. The baby’s major systems form and continue to become ready for entry into the world.

Answer:
First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called a blastocyst. Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.
