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.
The inside of the uterus is lined with the "endometrium" which is shed every month if you are not pregnant. Once you get pregnant that lining changes to the "decidua" which stays in place because of the hormone progesterone and hCG the pregnancy hormone during pregnancy.
The uterus lining will come loose and a mentral cycle will begin.
The lining of the uterus breaking apart is the mucus lining that is usually formed so as to create a conducive environment for a fertilized egg to develop. If the ovum is not fertilized, the thick lining breaks apart which is what causes menstruation.
Pregnancy occurred.
If you bleed during pregnancy it's not menstruation. It can sometimes seem like it but it's not. And it's usually lighter. If you are menstruating however you can not be pregnant. You menstruate because the uterus is shedding the lining since no egg is fertilized and attached to it. When pregnant you do not release eggs and the uterus can not shed the lining since then you would have a miscarriage.
After fertilization, the egg implants in the lining of the uterus. It can implant on any side of the uterus where the endometrial lining is thick enough to support pregnancy.
If you have a D and C while pregnant the fetus will be aborted. A D and C stands for the uterus to be dialated and the lining to be cut. or scraped to rid the uterus of the lining
We have a menstrual cycle so that we can get pregnant and continue humankind.Every cycle we ovulate and the uterus lining plumps up in preparation for possible pregnancy, if we don't fall pregnant the uterine lining sheds to allow the whole cycle to start afresh again.

Biologically, it is said that in menstruation the uterus 'weeps', as there is no pregnancy. The lining of the uterus is shed in the menstruation. Uterus is ready to have fresh lining of the uterine wall through next menstrual cycle.
The lining of the uterus thickens in preparation for a potential pregnancy. This thickening is mainly regulated by estrogen and progesterone hormones. If a fertilized egg implants in the uterus, the thickened lining provides a nourishing environment for the embryo to grow.
