The Week 4 begins like every other week. This is because there is a bit 'of time before you know if you have missed your period. Although, everything outside looks normal, your body is undergoing major changes to accommodate the growing baby in your womb
Following ovulation, fertilization and conception taking place successfully .; the fourth week blastocyst is firmly rooted in her uterus. This is the time for more advanced development of your baby. Normally, the body would be getting ready for the next menstrual period from now; but pregnancy will trigger new hormonal secretions that prevent this from happening.
Let's take a detailed look at what is happening inside your body when four weeks pregnant.
Word Precautionary:
Before you start reading this article, remember that every child and pregnancy is unique and this is just the general information of what takes place during four weeks of pregnancy. Your pregnancy or your baby's development can be little or more different from the data here; that does not need to be a cause of concern for you.
changes taking place inside your Body:Sponsored
The period of two weeks after your ovulation is known as the luteal phase. Corpus luteum, which is a collapsed follicle that is left behind after releasing the egg, plays an important role in the changes that occur in your body during this period. So this stage is known as the luteal phase.
The corpus luteum increases the production of progesterone, which in turn warms the body and the uterus for the embryo. Simultaneously, the endometrium thickens and increases the blood supply that creates a soft cushion as a condition for taking the blastocyst when it arrives.
Your brain has already been informed by your reproductive system to stop the process of menstruation. Your body means what is best for your fetus through hormonal signals and triggers.
Another big change is observed in your body is the secretion of hCG (human chorionic gonadotropin) hormone. The level of hCG in your body increases rapidly during the first few weeks of pregnancy; it doubles almost every day. This hormone is responsible for the pregnancy detection pregnancy test
interior of the uterus :.
With the onset of gestational four weeks of pregnancy, the blastocyst is comfortably settled in your uterus. Her uterus has undergone enough changes and made the epithelium of the uterine wall suitable for the reception of the blastocyst. If the endometrial epithelium is not properly prepared for implantation, the blastocyst will not succeed in attaching to it.
The single-cell zygote that was created a few days ago is now composed of an inner cell masses that constitute embryoblast, trophoblast and a primary yolk sac from the 4th week of pregnancy. The embryoblast will develop into an embryo and trophoblast will develop into the placenta.
At this point, a second cavity has appeared within the inner cell mass which then widens to become an amniotic cavity. Most of the cells that make up the amniotic cavity come from the inner cell mass, but some cells are borrowed from the trophoblast.
The placental cells are tunneling away in the lining of the uterus with their microscopic tentacles known as chorionic villi. The placenta can become fully operational by the end of the week, but it is currently not able to provide nutrients and remove waste products from the developing foetus.
Slowly the placenta starts to grow and incorporate into the uterine wall. It is composed of two distinct layers at this point. The placental cells are implanting and creating space within the lining of the uterus so that there is created a channel for the blood to flow developed inside the placenta.
The amniotic sac protects the fetus from amortizing a possible harmful pressure which may arise inside the womb with the comfortable, as well as prevent dehydration of fetal tissues. The yolk sac transports nutrients to the fetus, because the placenta will take time to develop. It also begins to produce red blood cells

connection with your Baby:
Your small child who is now a fetus is to establish its connections with you to grow long projections in the uterine wall. Is not it amazing? The tiny little hair like tendrils that wrap around the abundant small blood vessels in the lining of the uterus, will develop into a placenta. This is the time in which the embryo will develop a membrane around itself which is also the inner layer of the placenta developing.
The membrane known as chorion, establishes a connection between the uterus and the baby, which will continue until the baby is born. The tendrils provide oxygen and nutrients to the growing fetus until the placenta is fully formed. From now on, it is responsible for the provision of oxygen and nutrients to the developing baby to survive. It is a big responsibility, but fortunately nature has made every mother in shape to carry that task with natural ease
changes in your child :.
your baby is rapidly reaching the embryonic stage during the 4th week of pregnancy. Although there has been a rapid cell division, everything the child is able to reach the size of a pin. The current epiblast and hypoblast during this phase will develop in the body and the organs of your baby. All of the zygote cells were identical up to the eight-cell stage, but then began to form in embryonic stem cells. The fetus begins to operate by the end of week 4, with the help of the nutrients and oxygen supplied from the mother's blood.
During four weeks of pregnancy, embryonic stem cells have a choice to develop into any specialized cell that is necessary for the child's growth. They may develop in nerve cells, blood cells or muscle cells at this stage, but once they become specialized, must only perform their function. They can not change to any other type of cells after this stage. From the stage of 8 identical cells, now these cells can form all the different fabrics required by the growth of the child
Switching genes :.
No matter what the IQ of your child is going to be after the birth, at this stage the child is performing a great task to switch genes on and off with a high degree of accuracy, precision and complexity. The cells at this stage are called specialized cells off because the genes which are not needed, and turn on the genes that are needed to run a specific cell.
Muscle cells have all genes, with the exception of the genes necessary to produce the proteins of muscle cells. The same applies to all of the specialized cells that inactivate genes that do not require for the specific function. The cellular actions of switching on and off of growth factors continues at specific times and places as indicated by signals sent from the embryo, or precisely by this genetic code in it.
The small miracle:
Imagine the tiny embryo embedded in your breast that are tuning the signal strengths and turning the switch of the growth factors and receptors on or off depending on the need, depending on their position. This is one of the greatest miracles of the rapid development taking place inside of your womb.
The child is already establishing their identity in your lap. Even from the very early stage of pregnancy, the blood of your body does not mix with your baby's blood. The placenta pays the gatekeeper in this situation. The vascular network of your baby is developing and carrying out the functions of transporting blood, oxygen and nutrients from you blood flow through the umbilical cord
Size of your child :.
Finally, by the end of week 4, one child can be measured, although it is very small. The embryo is just a set of measurement 0.4 mm or 1/25 th of an inch cells, but is already functioning as a human being. Imagine the long journey your fetus has taken from being just a hollow sphere, with only a few cells growing as a group in this phase. This is a giant step

Care and suggestions :.
four Week is the time when the scene was set for the development of the heart of the child, head, brain, spinal cord, tissue, hair, organs, teeth, muscles and bones .

The correct folic acid supplement during pregnancy can reduce the risk of this congenital developmental disorder caused by the incomplete closure of the embryonic neural tube by 70%
- Switch on the duty of cleaning the cats or other pets to some other member of your family. cat feces can cause toxoplasmosis in you, which is a widespread infection with a parasite called Toxoplasma gondii. Generally the infection causes a mild, asymptomatic disease in people with a healthy immune system, which is not harmful. But it is dangerous during pregnancy because the parasite can infect the placenta and her unborn child.
Even after the safety system in the uterus, the possibility of you have an early miscarriage is about 20-30%. So take care of yourself during the fourth week, avoiding activities and food that can felicitate the unfortunate event
