Why are the interactions of hormones and tissues in the menstrual cycle considered to be feedback mechanisms?

The interactions of tissues and hormones in menstrual cycle are considered to be feedback mechanism because

when tissues tell the body to either activate hormones or stop hormones such that menstrual lining has the required thickness.

Arteries they do constrict and rupture. The initial purpose of the menstrual cycle is to make follicle stimulating hormone initiates the information of the follicle luteinizing hormone assists follicle stimulating hormone in the formation of the follicle, and then develop its ability to secrete estrogen and progesterone.

Estrogen passes into the blood and it travels to pituitary gland where the production of follicle stimulating hormone is turned off and this is termed as negative feedback.

The presence of estrogen in the blood stimulates the luteinizing hormone production and this is positive feedback.
