The fertilized egg takes a day or two roche co travel through the fallopian tube into the uterus, with the cells dividing along the way. During this time, it is called a morula and then a blastocyst as it grows. By the time the ball of cells reaches the uterus, it has separated into two layers. The inner layer will become the embryo, and the roche co layer will become the embryonic sac and placenta.

Once the blastocyst reaches the uterus, about six to 12 days after fertilization, it embeds itself into the lining of the uterus. This begins the embryonic stage of pregnancy. At this time, the embryo goes through a lot of basic roche co. The spinal cord, brain, and gastrointestinal tract begin to develop. The ball of cells is now an embryo and about the size of the head of a pin.

Arm and leg buds become visible and look like paddles. The heart begins to beat, and the placenta has started to form. Early structures that become eyes and ears have started forming. By roche co end of the fifth week, the embryo is made up of three layers of roche co. The top layer becomes your baby's outer layer of skin, parts of the nervous systems, roche co, the inner ears, and some connective tissues.

The middle layer of cells becomes the heart and circulatory system. Some of this cell layer roche co the base for the baby's bones, kidneys, muscles, and parts of the reproductive system. The inner layer of cells becomes a tube lined with mucous membranes. From this, the lungs, bladder, and intestines form.

The embryo grows rapidly this week. The heart is beating, and if you have a vaginal ultrasound, you may be able to hear a heartbeat. Today brain roche co to form, and its complex parts are beginning to develop. The embryo is starting to roche co basic facial features such as the jaw and nose.

The lungs are also beginning to grow. These eventually become toes and fingers. Even roche co and nipple follicles are starting to form, along with eyelids and the tongue. The embryo is about the size of a pencil eraser and weighs less than an aspirin. She is about one inch long. She moves around a lot now, but you cannot feel it roche co. The eyelids and ears continue to develop, as roche co the toes.

Ten weeks marks the end of the embryonic period and the start of the fetal period. The fetus measures about three inches long and weighs about one ounce.

Genitals have formed into clearly male or female, but they still cannot be distinguished on an ultrasound.
