3 Weeks Pregnant | What To Expect


(upbeat music) – Congratulations! You’ve conceived. One tenacious little
sperm ran the gauntlet, penetrated your ready egg
and presto, you’re pregnant. Your soon-to-be baby has
started its miraculous transformation from one
single cell to fully formed baby boy or girl, ready
for cuddles and kisses. Within a matter of hours after conception, the fertilized egg, called
a zygote, divides into two, then splits again and again. 72 hours after fertilization,
your little zygote has become a ball of 16 cells. This microscopic globe is called a morula, Latin for mulberry. And if you think about
it, that ball of cells does look like a berry-a cute little berry that you’ll soon be calling baby. Over the next few days,
the morula continues to drift down your fallopian tube, dividing into a blastocyst. A cluster of cells
numbering nearly 100 strong. Its final destination, your
uterus, which it’ll call home for the next nine
months as it morphs from blastocyst to embryo, to fetus, to baby. Amazingly, the blastocyst already has two distinct cell types. First, there’s the
outer trophoblast cells. They’ll become the placenta,
your baby’s lifeline during his stay in your uterine cocoon. The second type of cells
is called the embryoblast. This inner-cell mass will
eventually develop into your baby. Hard to believe, huh? Though it’ll be a while before
you’re able to tell whether your tiny blob of cells is
a boy blob or a girl blob, its gender has already
been determined by dad, or actually by his chromosomes. Mom always supplies an X
chromosome, but the proud papa provides either an X or a Y chromosome. Two Xs make a girl. An
X plus a Y makes a boy. In a few months, you’ll
be able to find out what winning letter combination you have growing inside of you. (upbeat music)

  1. Heya, If you are worried
    about diabetes the best results that I have ever had was with Blood
    sugar sniper (just google it) Without a doubt the most useful system
    that I have found to help start reversing it.

  2. Well, I'd say when a woman's baby has conceived, the baby in that woman's fallopian tube would be just a micrometre smaller than the width of a human hair, or the tip of a sharp pencil.
