How babies are made
To get pregnant you will need to ovulate (release an egg) and a one sperm from your partner will have to fertilize that egg. Once an egg is fertilized it will rapidly start to grow and the cells will start dividing. A fertilized egg is called an embryo. The embryo will then have to travel to the uterus and implant into the thick lining of the uterus. Once implanted the embryo will continue to grow. A placenta and amniotic sac will begin to form and grow.
The embryo will become a fetus at 9 weeks gestation. The fetus will rapidly grow and develop until it reaches full term around 40 weeks gestation.
