3rd Week Of Pregnancy What To Look Forward To
You are now pregnant, well done! The third week
of pregnancy is marked by a remarkable
transformation inside your body. Find out how the
egg and sperm unite in one of your fallopian
tubes. The fertilized egg then lodges in your
womb. If you have had more than one egg
fertilized during ovulation, the result could be
twins, or in extremely rare cases triplets. The
third week of pregnancy is too early to feel
clear symptoms like morning sickness - which
usually starts around the sixth week of pregnancy.

Fertilization process survival of the fittest
  • The sperms journey to fertilization has to be
    completed within 12 to 48 hours, before the sperm
    die. Many sperm envelop the egg in the fallopian
    tube. The head of each sperm releases an enzyme
    that tries to penetrate the egg.
  • Once a sperm has penetrated the egg, the cell
    membranes of the egg change its characteristics.
    They puff up and shove the remaining sperm far
    away from the egg. This guarantees that only one
    sperm fertilizes the egg. The remaining sperm die
    within 48 hours.

Fertilization process survival of the fittest
  • Identical twins form if the single fertilized egg
    splits into two. Fraternal twins develop when two
    eggs are fertilized by two separate sperm.
  • It takes around 60 hours for the zygote to reach
    the uterus by which time the zygote has
    multiplied to 60 cells. Each cell has a
    predetermined function in the scheme of things.
    The inner cell forms the baby. The outer cell
    layers form the membranes and placenta that
    nourish and protect your baby.

Fertilization process survival of the fittest
  • By approximately three days after fertilization,
    the zygote has about 12 cells. The dividing
    zygote in the fallopian tube slowly gets pushed
    along to the uterus. The fallopian tube is lined
    with hair like structures called cilia. They are
    responsible for pushing the zygote down the
    fallopian tube.
  • The fertilized egg is now called a zygote. Once
    the nucleus from the egg and the nucleus from the
    sperm unite, cell division takes place
    immediately.

Fertilization process - survival of the fittest
  • By four days after fertilization, the zygote has
    about 100 cells and is called a blastocyst. The
    blastocyst reaches the uterine lying, and floats
    for two days before finally implanting in the
    uterine wall. All this takes approximately a week
    to happen.
  • Once implanted the blastocyst secretes a hormone
    called HCG which indicates that a successful
    pregnancy has begun. The implanted blastocyst
    continues developing in the uterus for nine
    months.

Find out about the changes in your body this week
Experts suggest its too early to confirm if you
are pregnant at this stage. They advise its
better to wait another week or so before
pregnancy tests can be done. Some women swear
they could tell that they were pregnant at this
stage. Maybe this is what they call a womans
intuition.

How to take care of yourself during this exciting
week
  • Change in emotions You may want to hurry up
    things and find it difficult to wait to know if
    you are pregnant. To cope with such feelings
    remind yourself that your feelings are normal.
    Its natural for you to worry about the crucial
    development stage of your baby.
  • Dental check ups Be careful of getting dental
    x-rays at this stage. Advise your dentist you may
    be pregnant so that they can take suitable
    precautions.

How to take care of yourself during this exciting
week
  • Your surroundings Be wary of risks like germs,
    pesticides and poisons which can have an effect
    on the fertilization process.
  • Prenatal vitamins Its vital that you continue
    taking your vitamins making sure you are getting
    enough folic acid to avoid neural tube defects at
    this stage.
  • Change old habits Stay away from caffeine,
    alcohol and smoking. If you are on medications,
    check with your doctor, if its safe to continue
    taking them.
