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.

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.

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.
