week 4 - a poppyseed.



In week 3, sperm meets egg, and voila: conception! Your little zygote sets off on a six-day trek through your fallopian tubes, dividing and redividing into identical cells as it travels to your uterus.


In week 4, now safe in your womb, the ball of cells (blastocyst) splits in two, becoming the embryo and the placenta. The amniotic sac and fluid are forming around baby, and will act as a cushion for the next eight months.

This may help:

Conception: Fertilization of an egg by sperm. The fertilized egg (zygote) then attaches to the uterus, resulting in pregnancy.

Fallopian tubes: Two tubes, attached to either side of the uterus, that deliver eggs from the ovaries to the uterus.

Zygote: A fertilized egg.

Uterus: Female reproductive organ that holds and nourishes the developing fetus.

Embryo: The developing fertilized egg during the first eight weeks after conception.

Placenta: Organ that provides nourishment, eliminates waste and filters blood between the fetus and mother.

Amniotic fluid: Protective liquid in the sac surrounding the fetus.

Here is what LL 2.0 looks like this week in my ute.
