Baby of 4 Weeks Pregnant

Size

Your fertilised egg, known as a zygote, which is more like a ball of 32 cells, is about the size of a poppy seed. The baby is approximately 0.01 inches long and weighs approximately 0.04 oz.

Development

Now, there are three layers in your baby’s body: ectoderm, mesoderm, and endoderm. These layers will be converted into organs and tissues.

The inner layer (ectoderm) will form the nervous system, skin, hair, nails, mammary glands, sweat glands, and enamel for the teeth.

The middle layer (mesoderm) will develop into the heart, circulatory system, skeleton, connective tissues, blood system, and muscles.

The outer layer (endoderm) will give shelter to the lungs and convert into the lining of the gastrointestinal tract, pancreas, thyroid, and liver.

Arm and leg buds will start developing during this week, even though they are not exactly clear.

Other necessary things that will develop are the amnion and the yolk sac. The amnion is filled with amniotic fluid, which collects around and shields the growing embryo.

What happening in the body

During this time, the embryo itself implants itself in your uterus. Some women may feel cramping and spotting, while some may not feel anything. The amniotic cavity and the placenta start forming in the body.

Human Chorionic Gonadotropin Hormone

After the implantation of the embryo, a hormone known as HCG begins to form which maintains the lining of the uterus.

This hormone also gives the signal to the ovary to stop releasing an egg per month, which happens normally.

This is the hormone that creates the symptoms of pregnancy. Tiredness, aching breasts and nausea can occur with premenstrual syndrome (PMS).
