Every month the uterine lining is prepared for the pregnancy. Every month it is shed up. Changing of the lining is routine phenomena all over the body. The pregnancy is supposed to be the most precious lining. You can not expect the nature to use the same ling for years together, when the fresh one can be made available easily.

You can think of the uterus as a garden. It builds up the lining like a gardener adding mulch so when she plants seeds, they will grow well. The same goes for the newly fertilized egg.
When you have your period, the lining of your uterus sheds along with blood. This lining is made up of tissue and blood vessels that build up in the uterus each month in preparation for a potential pregnancy. When fertilization does not occur, this lining is shed during menstruation, resulting in a mixture of blood and tissue being released out of the body.
The presence of cells in the uterus or womb is normal and necessary for the proper functioning of the uterus. The lining of the uterus is made up of cells that build up and shed during the menstrual cycle or support the growth of a fertilized egg during pregnancy. If abnormal cells are detected, it may indicate a health issue that requires further investigation.
The lining of the uterus builds up between day 5 and day 14 of the menstrual cycle in preparation for a potential pregnancy. This build-up of tissue is influenced by hormones like estrogen and progesterone released during this phase of the cycle, creating a suitable environment for a fertilized egg to implant and develop. If pregnancy does not occur, this lining is shed during menstruation.
No, not all of the lining of the uterus comes out during menstruation. The shedding of the endometrium (uterine lining) is what causes bleeding during your period, but it does not all come out at once. Some of the lining is still attached to the uterine wall and will continue to shed in subsequent cycles.
the uterine lining builds-up during the proliferate phase of the menstrual cycle. Everyone's menstrual cycles are different, but during a 28 day cycle this phase would be around days 16-28.
Because of the effect of hormonal birth control methods on the lining of the uterus, the lining doesn't build up, and so doesn't need to be shed. So the blood didn't "go" anywhere; instead, it never "showed up."
Progesterone doesn't start your period, it's actually the drop in progesterone that starts your period. Progesterone caused the uterus lining to build up, if pregnancy doesn't occur the progesterone level drops causing the uterine lining to break down - menstruation.
During menstruation, the blood comes from the shedding of the lining of the uterus. The lining builds up throughout the menstrual cycle in preparation for a potential pregnancy, but if pregnancy does not occur, the lining is shed and expelled from the body as menstrual blood.
The urterine lining thickens during menstruation in order to shed, making way for the new layer to build up in hopes of a zygote burying into the wall.
