Answer 2

hormone levels drop, and the thickened lining of the uterus is shed during the menstrual period. Day 1 starts with the first day of your period. This occurs after hormone levels drop at the end of the previous cycle, signaling blood and tissues lining the uterus (womb) to break down and shed from the body.
