A nurse is educating a client about the menstrual cycle and the monthly hormonal changes that occur. Starting with day 1 of the menstrual cycle, please place the following four hormones into chronological order in which they rise during the menstrual cycle.

Rationale: Day 1 (Menstrual phase): FSH rises first to stimulate follicle development in the ovary. As follicles grow, they secrete estrogen, which rises next and leads to thickening of the endometrium. Rising estrogen levels trigger a mid-cycle LH surge, which induces ovulation. After ovulation, the corpus luteum forms and secretes progesterone, which rises to support implantation and maintain the endometrium.
