During Pregnancy the uterus gets totally focused on protecting and nourishing the growing foetus. This means it can't receive eggs as usual because the hormones sent to release the eggs, are being redirected to develop a baby. So, figuratively speaking, it sends out a busy signal. During pregnancy, your body temporarily halts ovulation and stops shedding the lining of the uterus. As a result, you don't have your period. After the baby is born, the body's natural cycle of ovulation returns, and your period returns as well.
The endometrium is a special type of tissue that usually lines the inner walls of a womans uterus. During ovulation, it fills with blood so pregnancy can be possible. During early pregnancy, the fertilized egg implants itself there. A little later, a placenta grows there. The endometrium nourishes the placenta and the fetus which the placenta protects.
It is more common for a womans menstrual cycle to cease when she becomes pregnant, however many women do continue to have a period throughout thier prenancies. Goes both ways, depends on ths individual little lady
The female uterus is always preparing to take care of a baby, so it starts forming a protective and insulating layer of flesh, blood, and other substances. When you don't get pregnant, though, the uterus does not need this coating of protective layers, so it excretes it through the vaginal opening, and that is your period.
It ceases until the end of the pregnancy.
If the egg is fertilized and results in pregnancy then the menstrual cycle stops. The menstrual cycle exists to allow pregnancy to occur, so when pregnant no need for it to continue.

During the menstrual cycle an egg is released and to prepare for possible pregnancy the uterus lining plumps-up, if pregnancy doesn't occur the uterus lining sheds (menstruation) so it can start afresh again next cycle.
