The Uterus
The uterus is a female reproductive organ where a fertilized egg implants and grows into a fetus during pregnancy. It is where the lining thickens and sheds during the menstrual cycle if pregnancy does not occur.
The uterus is the hollow muscular organ that protects and nourishes a developing fetus during pregnancy. It is located in the pelvis and has a lining that thickens each month to prepare for a possible pregnancy.
During a woman's menstrual period, uterine tissue sheds and is expelled from the body. This tissue, known as the endometrium, thickens and prepares for a potential pregnancy each month. If pregnancy does not occur, the endometrium is shed during menstruation.
Name of that hormone is 'Estrogen'. It is called as 'Oestrogen' in British English. It prepares the uterus for pregnancy. It is secreted by the follicles in the ovary.
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.

Menstrual cycle is about 28 days that prepares the body for pregnancy.
It thickens with tissue and nutrients to prepare to sustain a fertilized egg. This is what is shed during menses and what is seen, as the egg is virtually undetectable by itself.
