During fertilization, the sperm undertake a long and perilous journey into the woman's body. Their quest is to cross the cervix before they die. Out of millions of sperm, only one will fertilize the egg. Once that one sperm crosses the threshold, an entirely new journey begins.
For the next 40 weeks or so, the mother's body will undergo a series of transformations as it nourishes and houses a new life. The egg will also transform -- from a tiny mass of cells into a living, breathing baby.
In this article, we'll look inside the womb to learn how the fetus develops during each trimester of the pregnancy, see how the baby finally makes its way into the world, and find out what could go wrong during pregnancy.
