When Are Progesterone Levels Checked? Your progesterone level is usually checked six to eight days after you ovulate (about day 21 of a day 28 cycle). This is because progesterone levels rise following ovulation, peaking five to nine days after ovulation. This is known as your luteal phase. After the midluteal period, your serum progesterone levels will begin to fall if the egg is not fertilized.
The importance of the luteal phase. The purpose of the luteal phase is to produce progesterone that prepares a womanâs body for pregnancy. The length of this phase is usually constant and can be used to establish the time of ovulation with the womanâs menstrual cycle. This is important in planning or avoiding pregnancy. simple example is seen with a 28-day cycle and a luteal phase that is twelve days long. According to this information, ovulation should take place on day sixteen of the cycle. The calculation used to determine this date is the days of the luteal phase (12) subtracted from the days of the cycle (28).
