Knowing the length of your luteal phase allows you to more accurately predict at what point in your cycle ovulation occurs.


This is important information when you’re trying to conceive because of the small window of time each month during which you are most fertile: two to three days before you ovulate and for about 12 to 24 hours after ovulation.


The luteal phase is the second half of your menstrual cycle, when fertilisation and implantation may occur. This phase begins directly after ovulation and ends at the commencement of your period.


Your body temperature increases during this phase to create the optimum environment for pregnancy.


Typically, the duration of the luteal phase lasts between 10 and 16 days and is generally consistent from cycle to cycle, averaging for most women at 14 days. We have used this average as the default luteal phase length in the Essential Baby Ovulation Calculator.


If you would like to find out how long your luteal phase actually is, use our Basal Temperature Chart to make a daily record of your body temperature to determine your luteal phase length and predict the day of ovulation.
