you have your period.
The stage of the menstrual cycle during which blood, tissue, and an unfertilized ovum are discharged is known as menstruation, or the menstrual period. This occurs in the beginning of the menstrual cycle when the uterine lining sheds due to the absence of a fertilized egg.

At the end of a menstrual cycle, the unfertilized egg is either absorbed by the body or expelled during menstruation. The lining of the uterus, which thickened in preparation for a possible pregnancy, sheds as menstrual bleeding. This marks the start of a new menstrual cycle.
