FSH phases of the menstrual cycle occur during the follicular phase of the ovarian cycle.
Every woman has a different menstrual cycle, which is measured from the first day of one period to the first day of the next. Every 21 to 35 days, menstrual flow may occur, lasting two to seven days. Long cycles are typical in the first few years after menstruation begins.
Menstruation, the follicular phase, ovulation, and the luteal phase are the four stages of the menstrual cycle. Premenstrual syndrome and painful or heavy periods are common menstrual issues (PMS). The likelihood of pregnancy can be increased by understanding the time of the menstrual cycle when a woman is most likely to conceive.
