Several factors can influence the timing and duration of the fertile window, including:
Cycle Length: Women with shorter or longer menstrual cycles may ovulate earlier or later than the typical 14-day mark. Stress: High stress levels can disrupt hormonal balance and delay or advance ovulation. Health Conditions: Conditions like polycystic ovary syndrome (PCOS) or thyroid disorders can affect ovulation. Medications: Some medications, particularly hormonal treatments, can impact ovulation and the fertile window.
