An egg is released from one of your ovaries and the lining in your uterus gets thicker. Over the next couple of days the egg or ova travels down the Fallopian tubes. If it doesn't meet the sperm on its way to the uterus, your body gets rid of the lining and the egg by flushing it out through the vagina. If the ova is meet by sperm then the newly fertilised egg buries itself in the lining and starts growing. Here's a good sight that has a voice over video that explains it in more detail.
Menstruation
Labor and delivery.
The uterus is the part of the female reproductive system that nourishes and develops the fertilized egg. After fertilization, the egg implants in the lining of the uterus where it continues to grow and develop into a fetus.
That would be the uterus, my good fellow. Or the womb.
During the menstrual cycle, the endometrium of the uterus thickens in preparation for a possible pregnancy. If fertilization does not occur, the endometrium sheds during menstruation. The uterus also contracts to help expel the menstrual blood.
An egg gets fertilized in the fallopian tube by a sperm, then it goes inside of the uterus, and inside the uterus it develops.

Uterus
A fertilized egg develops in the uterus after it leaves the oviduct. It implants into the uterine wall where it continues to grow and develop into an embryo.

It develops in the uterus if it is nurtured by sperm.
