Pregnancy By Weeks
This is a comprehensive guide to understanding the different stages of pregnancy. It covers the development of the embryo and fetus, as well as changes in the mother’s body.
Weeks 1-2
The first two weeks of pregnancy are the time of conception. The sperm and egg unite in the fallopian tubes, and the embryo begins to form. The zygote contains all the genetic information needed to create a human being.
Weeks 3-4
The embryo begins to divide, and by the third week it has formed a small ball of cells. The embryo attaches itself to the wall of the uterus, and the placenta begins to form. The placenta is responsible for delivering nutrients and oxygen to the baby, and removing waste.
Weeks 5-6
The embryo continues to grow and develops into a fetus. The baby’s heart begins to beat, and arms, legs, and a brain begin to form. The fetus is only 1/4 inch long, but all of the essential organs have begun to develop.
Weeks 7-8
The fetus continues to grow and develops more features. Fingernails, eyelashes, and the start of hair appear. The fetus can now make small movements, and the mother can feel the baby’s kicks and punches.
Weeks 9-10
The fetus continues to grow and develop. By the end of the tenth week, the baby is about 3 inches long and looks like a miniature baby. The brain is growing rapidly, and the baby can hear and taste.
Weeks 11-12
The fetus continues to grow and develop. By the end of the twelfth week, the baby is about 5 inches long and weighs about 1/2 an ounce. The baby’s skeleton is starting to form, and the umbilical cord is functioning.
Weeks 13-14
The fetus continues to grow and develop. By the end of the fourteenth week, the baby is about 6 inches long and weighs about 1 ounce. The baby’s skin is thin and translucent, and the eyes and ears are fully formed.
Weeks 15-16
The fetus continues to grow and develop. By the end of the sixteenth week, the baby is about 7 inches long and weighs about 2 ounces. The baby’s lungs are maturing, and the baby can urinate and swallow.
Weeks 17-18
The fetus continues to grow and develop. By the end of the eighteenth week, the baby is about 8 inches long and weighs about 4 ounces. The baby’s muscles are getting stronger, and the baby can hear and see.
Weeks 19-20
The fetus continues to grow and develop. By the end of the twentieth week, the baby is about 9 inches long and weighs about 8 ounces. The baby’s skin is smoother, and the baby can grasp and suck.
Hcg Level For 5 Week Pregnancy
The hCG level for 5 week pregnancy is about 3,000-5,000 mIU/ml. This is the hormone that is produced during pregnancy and is used to detect pregnancy. The hCG level will continue to rise as the pregnancy progresses.
