menstrual cycles
Uterine lining shedding
The menstrual cycle is the roughly monthly hormonal process in which the uterus prepares for pregnancy.
If no fertilized egg implants, the uterine lining sheds as menstrual bleeding, and the cycle begins again.
The average cycle runs about 28 days, though this varies widely: My menstrual cycle has always been irregular.
