    When you are pregnant, your health and baby’s health go hand in hand. Whatever you consume or intake directly affects how your baby’s health is. Before pregnancy, there are some things you should always consider. These are:

    Avoid Drugs, Alcohol, and Tobacco

    These things are very serious when consumed during pregnancy. They can cause a defect in birth, Fetal alcohol syndrome, low weight during birth, respiratory diseases, and different health issues.

    This might sound stage to you but still, there is time for pregnancy. Fertilization of ovum and sperms will take place during this week’s end.

    The gender of the baby will be known after fertilization occurs. The chromosomes that will determine the baby’s sex are XX and XY.

    Changes Occurring in Your Body

    At this stage, the uterine line of the mother is still nourishing and developing to receive the fertilized egg. A female’s body releases or stimulates the secretion of FSH or follicle-stimulating hormone. This hormone itself is responsible for stimulating the egg for maturation. This week is most likely the week when you are about to conceive as the sperm penetrates the egg to form a zygote which further forms the embryo. You will not be seeing a lot of changes in the body yet.

    Week Three Pregnancy Calendar

    Changes In Baby in 3rd-week Pregnancy Calendar

    Even in the third week, you will not feel as if you are pregnant, but at this stage, the baby starts to grow and develop inside of you. After the process of fertilization, the egg that has been fertilized goes through a series of changes in the form of cell division. After completion of 30 hours from the fertilization, the cell divides itself into 2 cells, then 4 cells, then 8 cells, and so on when it moves within the fallopian tubes to reach the uterus line to get implanted. By the time it reaches the uterus, a group of cells that have been formed previously appears to be in the shape of a ball. This cell ball is known as a morula.

    Morula is filled with fluid and is hollow from inside. This hollow structure is called a blastocyst. At the end of near to the end of 3rd week, this structure called as blastocyst will prepare itself to attach to the inner lining of your uterus known as the endometrium. This process is known as implantation. During or after implantation light flow of blood might occur for 1 or 2 days, this is common in few women and is known as implantation bleeding.

    Implantation is very important as it forms a connection between the mother and child and is responsible to carry out nutrition to the baby and remove the waste materials produced at that site by the baby. This endometrium line further elongates to form a connection between mother and baby that we call as placenta or placental cord of connection.

    You need to make sure by this time that you are consuming enough amount of nutrients for the baby’s development. some important nutrients to take at this time are protein, iron, calcium, and folic acid. If your diet doesn’t contain any of these supplements naturally you can go for purchasing these supplements after consulting a doctor. The neural cord or tube of the baby develops at an early stage of pregnancy in the first few weeks. Folic acid consumption here becomes very crucial.

    Protein is responsible for creating new tissues that are very important in your baby. So consuming enough protein is important. Calcium aids in the formation of bones and teeth in the baby. Intake of iron is also necessary to increase the count of blood cells and healthy growth. Some food items that provide a good amount of calcium and iron include legumes, eggs, red meat, leafy vegetables, lentils, peas, beans, dairy products, etc.

    Development Of Baby In 4th-week Pregnancy Calendar

    after 4 weeks of pregnancy, your baby has become an embryo. This embryo has 2 types of cell layers. The two layers are known as hypoblast and epiblast. These layers are the only one that develops and forms your baby’s organs and different body parts growing exponentially.

    apart from these two layers, other structures also grow and develop into yolk sac and amnion. This amnion is completely filled with a fluid known as amniotic fluid and is responsible for surrounding and protecting the embryo formed. This yolk sac is responsible for producing blood and helping the embryos formed to get nourished until the placenta is formed. Later, the placenta performs the functions that the yolk sac now performs.

In case the bleeding doesn’t stop and pain becomes intolerable, it is highly advised to visit a doctor.

    After the process of implantation is completed the embryo prepares itself to produce a hormone called Human Chorionic Gonadotropin hormone or HCG. This hormone functions to maintain the lining of your uterus. After implantation or getting pregnant, you have realized and heard from everywhere that period cycle every month stops. The reason behind this pause for 9 months of pregnancy is HCG. It signals the ovary to stop producing any more ova.
