What happens during the menstrual cycle if hormone levels do not have their peak by day 14?

If hormone levels do not peak by day 14 of the menstrual cycle, ovulation does not occur. Therefore, the corpus luteum is not formed and the levels of progesterone do not rise. This results in the continued shedding of the uterine lining, leading to a longer menstrual period than usual. This is known as anovulatory bleeding and may indicate that the woman has an underlying hormonal imbalance or condition affecting ovulation, such as polycystic ovary syndrome (PCOS). In such cases, it is recommended to consult a healthcare professional for further evaluation and treatment options.
