Many people wonder how long is luteal phase when tracking their menstrual cycle. The luteal phase typically lasts 12 to 14 days, starting right after ovulation and ending when menstruation begins. Unlike the follicular phase, the luteal phase is generally stable in length from cycle to cycle. Understanding how long is luteal phase can help you track ovulation accurately, manage PMS, and improve fertility awareness. A consistently short luteal phase may indicate hormonal imbalances, while a longer phase could suggest early pregnancy. Monitoring your cycle and recognizing signs like temperature changes or mood shifts can help you determine the exact length of your luteal phase for better menstrual health.
