Determining Luteal Phase

The term Luteal Phase or the Post Ovulation Time is the amount of time between a female’s Ovulation Time up to the very first day of bleeding of the menstrual period. This is mostly fixed time in almost all women and being around 14 days.

The length of the Luteal Phase could vary by a day or more  but for each woman the luteal phase length is exactly the same length of time each month. The average amount of time of the Luteal Phase is around 14 days but some women could have a luteal phase of 15 days and some of 13 but for most women it’s 14 days long. The length of the Luteal Phase is constant even in women that have irregular periods.

For those women that experience irregular monthly cycles, the irregular part is actually the time from the beginning of the cycle (1st day of bleeding) up until the time of ovulation. Once ovulated then the period is guaranteed to start some 13 to 15 days after as long as fertilisation has not happened.
