I got this image and description from the Bump (aka, the Nest). They have these all throughout the pregnancy. I'm going to try to include them in my blog for interested readers.
"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."
However, tomorrow will already be week 5, so I'll get to post a new picture soon!
