during the menstrual cycle
Menstruation occurs at the start of the menstrual cycle and normally lasts around a week, so menstruation would occur days 1-7 of the menstrual cycle.
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.

Sperm is the male sex cell that goes on to fertilize the egg in order for pregnancy to occur. The menstrual cycle is the female reproductive cycle, an egg is released during ovulation.
Normal fluctuations occur as a result of puberty, the menstrual cycle, pregnancy, and menopause.
Menstruation is one of the phases of the menstrual cycle, whereas the menstrual cycle is the entire reproductive system. 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.
