One of the major hormones of pregnancy, estrogen helps maintain the endometrial lining of the uterus. Additionally, progesterone will also help to maintain the uterine lining.
Menstrual flow isn't just blood, the blood is actually secondary to the main waste material: uterine tissue. Basically the chunks are pieces of the uterine lining itself, or may be lumps of bloody mucus.

During Menstruation. The uterine lining sheds to prepare the uterus for pregnancy. It's due to the drop in estrogen and progesterone.
The uterus lining deteriorates during menstruation. The menstrual flow is the uterine lining that is shedding after pregnancy does not occur.
Some women have light bleeding during their pregnancy but it is not a period, a menstrual period is the shedding of the uterine lining - if the uterine lining sheds during pregnancy the embryo or fetus would be miscarried.
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.
Menstruating is the uterus basically not being pregnant and therefor getting rid if the uterine lining. When pregnant there is a fertilized egg and the uterus will protect it with the uterine lining.
Your period is the breakdown of the uterine lining. Once a pregnancy is established by the embryo implanting in the uterine lining, the hormone hCG and progesterone kick in to prevent the breakdown. While pregnant the lining does not break down because it is being used to support the placenta and fetus.
Corpus luteum secrets an hormone called Progesterone that maintains the lining of the endometrium and sustains pregnancy
Menstruation is what happens when a woman doesn't get pregnant - after ovulation the uterine lining builds-up in preparation for possible pregnancy, if a woman doesn't get pregnant then menstruation occurs to shed the uterine lining so it can start fresh next cycle. During pregnancy the uterine lining is busy keeping the growing embryo/fetus safe, and women no longer ovulate.
The uterine lining creates a place for the fertilized egg to attach to in the uterus. Once the egg has attached to the uterine lining, it begins to grow. The lining also helps deliver nutrients to the developing fetus.
Having a period (shedding of the uterine lining) and pregnancy are not compatible but some women experience monthly period type spotting during pregnancy.
It is the design of the nature to prepare the uterine wall for the expected pregnancy. The uterus sheds the wall during the periods. So that the fresh uterine lining can be prepared in next menstrual cycle.
