What process signals the end of one cycle and the beginning of another in the menstrual cycle

Respuesta :

shantevinson
A new cycle starts on the first day of her period, for 3-8 days. 14 days after the first day of the recent period, ovulation happens, & the lining builds up. 
So basically, ovulation. 

Hope that makes sense & helps. (:
