How does your baby grow in the womb? Fox News examines various developmental stages from conception to childbirth.
Pregnancy tends to have a well-understood and predictable course. However, according to experts at the Cleveland Clinic and Mayo Clinic, many are surprised to learn that the onset of pregnancy is about two weeks before the actual conception. The first day of a woman’s last menstrual period is the day when pregnancy is expected to begin. This is called gestational age or age of menstruation and is calculated by gestational age and due date according to the websites of both medical systems.
According to the Mayo Clinic, “Pregnancy usually occurs about two weeks after the onset of the last menstrual period. To calculate the estimated date, the care provider counts 40 weeks after the onset of the last menstrual period. So your period counts as follows: Part of your pregnancy-even though you weren’t pregnant at the time. “
For this reason, to avoid confusion, define a timeline from conception to development.
According to health professionals at both the Cleveland Clinic and the Mayo Clinic, the following developments have been made since conception:
According to health experts, the first trimester of a baby’s development is thought to extend 12 weeks after conception.
Conception by week 1:
Eggs begin to divide rapidly into many cells within 24 hours of fertilization. This is called a blastocyst and usually stays in the female fallopian tubes for three days. The fertilized egg continues to divide and then migrates and is transplanted into the female uterus.
2nd to 4th week after conception:
Within 3 weeks, the fertilized egg forms a small sphere and is called an embryo. By this time, the first nerve cells have been formed, according to the Cleveland Clinic. Embryos are now composed of three layers that lead to the development of some of the baby’s systems and organs.
According to the Mayo Clinic, the neural tube is closed four weeks after conception. The baby’s brain and spinal cord develop from the neural tube. The heart and other organs begin to form. The small buds that form the arms appear and the eyes and ears begin to develop. The embryo is about 1/4 inch long and has the shape of a C-shaped curve.
According to the Cleveland Clinic, a small “heart” tube beats 65 times a minute by the end of the fourth week.
5 weeks after conception:
According to the Mayo Clinic, the baby’s brain and face are growing five weeks after conception. Depression is seen, which helps the formation of the nostrils, and the retina of the eye begins to form. The buds on the arms sprout on the paddle and the buds on the lower limbs begin to form. The brain and face begin to grow.
6 weeks after conception
At the end of the six weeks, the baby could grow to half the diameter of the US quarter, according to the Mayo Clinic. The buds on the lower extremities begin to look like paddles while the upper lip and nose are being formed. The fingers begin to form, the contours of the ears develop, and the eyes become more visible.
7 weeks after conception
According to Mayo Clinic health experts, seven weeks after conception, the arms and elbows of the embryo grow as the toes and eyelids form.
8 weeks after conception
After the 8th week, the embryo is called a foetation until birth. The eyelids and ears develop and the umbilical cord can be seen. The toes and fingers are longer and the foetation can bend and move its elbows.
9-12 weeks after conception
Health experts say that at this point the baby is officially called a foetation. According to the Mayo Clinic, red blood cells begin to form in the fetal liver, the external genitalia begin to develop, and the intestines are in the abdomen.
The Cleveland Clinic says the foetation begins to open and close its fists and mouth at this stage. The arms, hands, fingers, feet, and toes are fully formed, and the fingernails and toenails are beginning to develop while the outer ear is being formed.
By the end of this first semester, the Cleveland Clinic says that all organs, arms and legs are present, the circulatory and urinary systems function, and the liver produces bile. According to the health system, the foetation is fully formed, typically 4 inches long and weighs about 1 ounce. At this stage, the Cleveland Clinic states that the most important developments have taken place and the risk of miscarriage has been significantly reduced after the first three months.
