Heartiest Congratulations for Conceiving!

Your journey as a Creator of life has begun.

Though you might have missed your period and tested positive for your pregnancy now, you have conceived around 14 days before, when your egg was released.

The fertilization i.e. the union of egg and sperm occurs within 24 hours of ovulation and 24-48  of ejaculation of sperms into vaginal tract following coitus.

The fate of genetic characters of the progeny including its gender (male or female) has been determined at the time of fertilization.

The ovum is always 23 X, whereas the sperms can be either 23X or 23Y. Hence, the sex of Zygote is determined by the contributing sperm of father (23X or 23Y) and not the ovum of the mother.

Since, it is not possible to predict the date of ovulation accurately, for all practical reasons, the expected date of delivery is calculated from the first day of last menstrual cycle (L.M.P).

In this short span of 2weeks, your baby has transformed from a single cell zygote to a multi-cellular embryo.

Journey from Conception:

Your baby had only 3 main targets to achieve in first 2 weeks after conception:

1- Proliferate its cells in both number and size.

2- Differentiation of cells for specific functions. 

3- Implant itself with the help of invading trophoblastic tissues into your womb to survive.

  • Invading trophoblastic tissue would soon develop into placenta to derive nourishment from your blood and excretes its waste.
  • The trophoblastic tissue produces Human Chorionic Gonadotropin (HCG) hormone, the level of which is detected in blood and urine to confirm the pregnancy.
  • Three germinal layers, endoderm, mesoderm and ectoderm which would give rise to all the organs of your baby.
  • Primitive Yolk sac is formed.

 It is a membrane-lined sac that provides nourishment in the early stages of a baby’s development until the placenta is fully formed. It also acts as a rudimentary circulatory system before the embryo is able to circulate blood internally. It produces the initial baby’s blood cells, much before their formation in bone marrow, liver and spleen. in which the first blood cells form. In fact, if you have a female baby, her eggs will form  from the endodermal lining of yolk sac, transmigrate to ovary and remain there life long for subsequent maturation. Toward the end of the first trimester, the yolk sac shrinks and can no longer be seen on the sonogram.

  • The baby is surrounded by the amniotic sac filled with amniotic fluid, that not only provides cushion to protect your baby from the injuries but also optimum environment for its adequate growth and development.
