The Luteal Phase is the time period that begins the day after ovulation and runs through the remainder of your menstrual cycle (ending the day before your next period). Typically, the luteal phase lasts between 10 to16 days and is consistent from cycle to cycle, averaging 14 days for most women.

Important Note: If you have a short luteal phase (10 days or less), this is considered a luteal phase defect. Luteal phase defect, which is typically caused by low progesterone levels, tends to lead to early miscarriages. Natural fertility supplements, like FertilAid for Women, tend to increase progesterone levels and may be beneficial for women with luteal phase defect.
