1. 3 Weeks Pregnant: A Peek Inside Your Womb

2. Congratulations! You have conceived. Your
baby is now developed in the form of tiny cells.

3. The fertilized egg will travel from the fallopian
tube to the uterus and start developing fetus.
The fertilized egg is called a zygote.

4. The zygote has all the genetic material, half of the
46 pairs of chromosomes from you and half from
your partner.

5. Mom supplies an X chromosome, but dad
provides either an X or a Y chromosome. At
this time, baby’s gender is determined by the
dad’s chromosomes.

6. 12 hours after fertilization, the one-celled zygote
further divides into two identical cells which will
then split to four then to eight and then to 16.
Now the cell is known as blastocyte.

7. The blastocyte takes up residence in your
uterus where the baby grows for the next 9
long months.

8. The part of blastocyte sloughs off to become a
placenta that provides nourishment to the fetus
through umbilical cord. Now the amniotic fluid
begins to collect around the blastocyte.

9. The newly implanted pregnancy produces HCG
hormone which triggers the production of
estrogen and progesterone.HCG is the chemical
which shows your pregnancy test is positive.
