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.

The presence of cells in the uterus or womb is normal and necessary for the proper functioning of the uterus.

If abnormal cells are detected, it may indicate a health issue that requires further investigation.

Why does the corpus luteum not stop producing its hormones when fertilization has occurred?

The corpus luteum continues to produce hormones (progesterone) even after fertilization to support early pregnancy until the placenta takes over hormone production. This is essential for maintaining the uterine lining for the implantation and development of the embryo. If fertilization does not occur, the corpus luteum will degenerate, leading to a drop in hormone levels and the start of menstruation.

Where does the blood go when you stop your period with the mini pill?

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."


How does progestrone start your period?

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.


Does the lining of your uterus always come out during your period?

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.


How does the wall of the uterus change during the course of the cycle and why?

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.


Is thickening the endometrium the main function of progesterone during menstrual cycle?

Yes, thickening of the uterine lining is one of the main functions of progesterone during the menstrual cycle, allowing the womb to build-up the uterine lining to support a fertilised egg. If pregnancy doesn't occur then it's the drop in progesterone that causes the uterine lining to break down.
