How many days before your period does the lining start to shed?
On day 14 (for most women), one of your ovaries will release an egg, which will make its way through a fallopian tube and will eventually make its way to your uterus (called ovulation). On day 28 (for most women), if you have not become pregnant, the lining of your uterus starts to shed. This is your period.

The four phases of the menstrual cycle are menstruation, the follicular phase, ovulation and the luteal phase.
Why did I shed my uterine lining?
Progesterone prepares the endometrium to receive and nourish a fertilized egg. If pregnancy does not occur, estrogen and progesterone levels decrease. The decrease in progesterone triggers menstruation, or shedding of the lining. Once the lining is completely shed, a new menstrual cycle begins.
