DEVELOPMENT
OF YOUR BABY ON 5-8 WEEKS:
Your baby is growing and changing. In the 5-8th weeks of your
pregnancy, your baby's cells differentiate and begin to undertake special
functions. This specialization process of cells is called differentiation.
Differentiation is important for the formation of different types of cells that
make up a human. As a result of differentiation, the outlines of your baby's
appearance have also begun to take shape.
5 WEEK
PREGNANCY
Until this week, your baby, consisting of a cell pile, is now
called an embryo. From the 5th week onwards, the body structure begins to form.
The embryo is divided into three layers. All tissues and
organs develop from these layers. A groove is formed in the top layer, which is
then closed to form the neural tube where your baby's brain, spinal cord,
spinal nerves and spine will develop.
The heart and circulatory system is formed from the middle
layer of the embryo. The heart develops from the bulge in the center of the
embryo. At the end of the 5th week, early blood elements and blood vessels are
formed in both the embryo and placenta.
Your baby's first heartbeats start 21-22 days after
fertilization. However, neither you nor your doctor can hear these heartbeats.
Only ultrasound can monitor heartbeat movements. With these changes,
circulation begins. The circulatory system is the first functioning organ
system.
Lungs, intestines, and bladder develop from the inner layer.
In the 5th week, only these structures develop from the inner layer. Other
organs will be formed after the development of these structures.
Immediately after fertilization, your baby is a single cell
zygote and is microscopic in size. In 5 weeks of your pregnancy (3 weeks after
fertilization), your baby is about the size of a pencil tip (about 1.5 mm).
6 WEEK
PREGNANCY
In the 6th week, development continues rapidly. Your baby's
dimensions increase about three times. Begins to show basic facial structures.
Optical vesicles begin to form, which will later turn into eyes. At the same
time, structures are formed, which are the precursors of the inner ear. Lips
will be formed through the opening formed by the tissues on the top and side of
the face.
In the 6th week, the neural tube located in the back of your
baby is completely closed. The brain grows rapidly and fills the newly formed
head. At the same time, special parts of the brain develop and some special
nervous structures become visible (cranial nerves).
40 small tissue blocks develop in the baby's midline, which forms
your baby's connective tissue, vertebrae, and muscles. Small bones in your
baby's arms and legs can now be seen.
In the 6th week of your pregnancy (4 weeks after
fertilization) your baby is about 3 mm.
7 WEEK
PREGNANCY
This week, the umbilical cord, which is the life link between
your baby and the placenta, is clearly visible in the womb area where the baby
is held. The umbilical cord contains two arteries and a large vein. Blood rich
in nutrients and oxygen passes through the placenta through your vein which is
unique to your baby and returns to the placenta through the arteries. This
circulation takes about 30 seconds for a single blood cell.
In addition, your baby's brain becomes more complicated. The
formation of cerebral cavities and pathways is important for the circulation of
cerebrospinal fluid. The developing skull during this period is transparent,
and the smooth surface of the brain can be seen when viewed with a magnifying
glass.
This week, your baby's face contains more details. Mouth
opening, small nostrils, ear structures and eye color can now be seen. The lens
structure of the eye is formed. The inner ear unites with the middle and outer
ear, opening to the outside world.
This week, your baby's arms, legs, hands and feet will form,
while the fingers and toes will be formed after about a week. Arm bud is
divided into hand and forearm sections. In this state, the arm looks like a
small claw.
Your baby is about 8.5 mm in 7 weeks of your pregnancy.
8 WEEK
PREGNANCY
Your baby's fingers and toes begin to take shape even though
they are stuck together. Arms and legs look longer and recognizable. The
claw-shaped hands and feet become clear. Knees, elbows and wrists are clearly
visible. It can even bend your knees and elbows.
Eyelids begin to form this week as well. Your baby's eyes are
open until the eyelids are formed. In addition, the upper lip, nose, and ears
become prominent this week.
The digestive tract, especially the intestines, continues its
development. Heart functions and circulation now show full development. During
this period, your baby's heart beats 150 times a minute (about twice the size
of an adult).
Your baby is approximately 12.5 mm in the 8th week of
pregnancy.
THREATS IN
THIS EARLY WEEKS
Your developing baby is very sensitive to external factors in
3-8 weeks after fertilization. This period is 5-10 of your pregnancy.
corresponds to weeks. All organs are formed during this period and damage to
the embryo can lead to serious birth defects such as spina bifida.
During this
period, the following can harm your baby:
TERATOGENES: These are substances that can cause physical
harm in the developing baby. Such as alcohol, certain drugs, narcotic drugs.
These should be avoided.
INFECTIONS: Viruses and bacteria can cause serious harm to
your baby in early pregnancy. Even if you don't feel sick, some of the
infections you are having can cause serious harm to your baby. Measles,
rubella, cytomegalovirus, toxoplasma are some of these diseases. Having these
diseases allows you to gain natural immunity.
RADIATION: High dose ionizing radiation (used in cancer
treatment) can cause serious harm to your baby. However, low dose radiation
(X-rays) used for diagnostic purposes does not pose a serious danger. However,
it is best not to be exposed to X-rays unless necessary. Do not panic if you
have been exposed to X-rays just before you know your pregnancy. Consult your
doctor.
ENOUGH NUTRITION: Advanced malnutrition can cause serious
harm to your baby. In this case, cell development will not be at the expected
level. However, in the early stages, embryo is not affected by low calorie
intake due to nausea and vomiting.
Taking 400 micrograms of folic acid daily reduces the risk of
spina bifida and other neural tube defects.
5-8.
CHANGES FROM THE MOTHER ON THE WEEK
The second month of pregnancy brings some changes in your
body. Complaints such as nausea, vomiting, weakness, insomnia, frequent
urination are common this month. Nausea-vomiting affects 70% of pregnancies.
This uncomfortable problem is typically 5-8. It starts in weeks and can
continue until the 14th week. These complaints are also a sign of a normal
pregnancy. Studies show that pregnant women with these complaints experience
less abortion. These complaints are known to be associated with increased hormone
levels in the body.
Your body produces more blood to carry blood and oxygen to
your baby. At the same time, the blood vessels expand and the heart works
faster and stronger. This change can lead to weakness, fatigue and headache.
With increased estrogen and progesterone, breasts grow and
milk-producing glands expand. The nipples are wider and the color becomes
darker. As a result, tension, tenderness and fullness may be felt in the
breasts.
Your first pregnancy is the size of a uterus pear in these weeks.
Over time, the uterus will grow to carry the baby, reaching about 100 times its
normal volume. The growing uterus puts pressure on the bladder, which can cause
you to urinate frequently.
During pregnancy, the cervix softens more and more. This
prepares the cervix for thinning and opening that will occur at birth.
You may experience vaginal bleeding for the first 12 weeks.
Statistics show that 40% of all pregnancies have vaginal bleeding. Again,
according to statistics, less than half of pregnant women with vaginal bleeding
are observed.
In the first two months, as soon as you learn about your
pregnancy, you may be afraid and anxious with the thought that you have harmed
your baby with the medications, nutrition and other factors you have been
exposed to during the two months you have not been pregnant. You may also have
doubts about whether you can be a good mother and whether you can bear birth
pains. Share all these concerns with your doctor.
HORMONES
Hormones are chemical messengers that make many arrangements
about pregnancy. Progesterone hormone is first produced in the ovaries and then
in the placenta. Progesterone prevents uterine contractions. It also matures
the veins in the wall of the uterus, which will allow the baby to develop. The
ovaries and placenta also produce estrogen. Estrogen plays a role in the
development of the uterus, cervix, vagina and breast.
